This is a very specific problem so it might only work for some. After I updated WordPress and all plugins on an old site that used WordPress Custom Fields to enter some data, the Custom Fields in admin disappeared. I could add a new post but Custom Fields were nowhere to be sen, not even in the screen options.
Long story short, after doing some searching on the net, I found out it was ACF (Advanced Custom Fields) fault. In new version of the plugin they disable WordPress Custom Fields because they think you are using ACF anyway so no need for both. Not sure I agree but here is 2 ways you can try to solve it:
- If you activated ACF but are not using the plugin, just disable it. WordPress Custom Fields should come back.
- If you want to keep both then add this code to your theme’s function.php file (the best is the child theme, if you have one)
WordPress Custom Fields should reappear now.
If you set up a global variable in the header you would expect that it would be available everywhere, right? That is the definition of the word ‘global;, right? Well, it doesn’t work like this and the reason is because in WordPress header and footer are called via functions so the variable is only accessible in scope of each function.
One of the solutions is simple – use global variable before the declaration AND before echoing.
For example, add this to
<?php global $var; $var= "something"; ?>
and then in the
footer.php you do this :
<?php global $var; echo $var; ?>
and it will echo the content of your $var variable.
Be advised though that some people say using global variables is not the best practice.
I am using Contact Form 7 on one of WP sites and after update (not sure which one) I started getting this error after user submitted the form:
‘Failed to send your message. Please try later or contact administrator by other way.’
As always, lots of way to complicated solutions on the net when, in my case, the solution was simple.
This is what I had before (CF7 admin):
And this is the one that works (I just replaced data in the FROM field):
of course you need to replace domain.com with your domain.
I do not know why did it worked before and why it stopped working but this is how I solved it. Of course you cant just hit reply now because your email is REPLY email. To solve this you can try this :
Contact Form 7 has a field called “Additional headers:”. Enter (literally)
Reply-To: [your-email] and save.
I wanted to update one of my WordPress sites from 4.2.2 to the latest but WordPress did not show me there is a new version available even though WordPress is already on version 4.3.
If this happens to you the first thing you should check is to see if there is this line in your
wp-config.php file :
define( 'AUTOMATIC_UPDATER_DISABLED', true);
In my case it was, so I set it to
false however it sadly didn’t resolve the issue.
If the same thing happens to you then I suggest you to install this awesome plugin (just look at the ratings):
It immediately found out that WordPress code files were modified by cPanel (most probably if you installed WP via your hosts cPanel), which added few lines to core files that prevent WordPress to show updates (something with incompatibility). Word Fence then offered a bulk replace and replaced these modified files with the clean WordPress core files. Refresh and WP immediately offered and found update to latest WP.
It is easy to get a post ID in WordPress. To echo it on screen we write:
<?php the_ID(); ?>
To store the ID into variable we use something like this :
$id = get_the_ID();
There is one caveat though: if you read the description on WordPress codex it says this in both cases: This tag must be within The Loop.
So if you ever wanted to retrieve or display the WordPress post ID in footer or header or outside of The Loop you might end up being disappointed because the ID returned is not the correct one (usually we always get the same id, most probably the last one?)
Now I am not going to go into technical details or why is that so here is the solution that worked for me. You
$post = $wp_query->post;
There are some other ways with global variables and some other but it seem it doesn’t work for everyone. This one worked on the first try. Let me know in comments if it doesn’t work for you.
There is nothing worse than getting blank screen when developing for WordPres – also ‘officially’ known as The White Screen of Death – because you have no idea what went wrong. No errors, nothing useful, just blank screen. It’s even worse when it just appears out of nowhere. This happened to me few times in the past and then just recently. Woke up in the morning and the entire site (not this one) displayed just blank white page.
First thing you should do is rename the
plugins folder and see if it works. If yes then the problem is in one of the plugins so if your admin works start disabling plugins one by one. If admin doesn’t work then try renaming plugin folders via FTP. If this doesn’t help then rename the
themes folder and see if the problem was caused by one of your theme.
This didn’t help in my case. So I went to WordPress site (link below) and insert the code they recommended! It STILL didn’t work and there were no errors displayed! So finally I modified the code a little and finally the error appeared! I don’k know why are they posting a solution that doesn’t display the errors.
Here is the code that started showing errors and I finally able to fix it. Still the mistery remains why did the blank screen start appearing when it was working just fine yesterday when I went to bed. Ah, the ‘joys’ of developing.
wp-config.php file in the root directory of your worpress and insert this just above the
/* That's all, stop editing! Happy blogging. */ comment. Refresh the WordPress and hopefully you will see PHP error telling you what went wrong.
// Enable WP_DEBUG mode
// Enable Debug logging to the /wp-content/debug.log file
// Enable display of errors and warnings
// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
After you fix the error don’t forget to remove or at least comment the added code.
In case it didn’t work, here are some more steps to try to fix it:
Common WordPress Errors and Debugging in WordPress
This is for WordPress but can be used in any site because it uses
I needed to redirect all visitors that visit the root URL (for example
elcoderino.com) to specific subpage (eg
elcoderino.com/subpage). WordPress allows you to create a static front page or select a custom page that will replace default front page content but in my case it just didn’t work. Maybe it was combination of Advanced Custom Fields or custom post types but it just kept messing up the front page.
So the solution is to add this to your
RewriteRule ^$ /subpage/ [R=301,L]
.htaccess file already contains
RewriteEngine On then simply just add
RewriteRule ^$ /subpage/ [R=301,L] below it.
I wanted to add custom buttons to WordPress editor so I installed Visual Editor Custom Buttons, made a new button (it’s really easy and intuitive) but when I wanted to create new post or page I encountered a problem: Visual Editor toolbar completely disappeared.
wp-content/plugins/visual-editor-custom-buttons/js). The problem was that plugin somehow fails to write (insufficient permissions) to this folder so it is unable to create these files. After you created a new button you should open the aforementioned
js folder and check if there are files named similar to
button-1-1.js. If not then this could be the problem. You will most probably need to delete and add the button again after you change the permissions of folder
js to 777.
The solution was to simply change folder permissions to 777 with FTP program (FileZilla : right click on folder and select File Permissions… option)
I used to use Xampp but I decided to try Wamp for my new WordPress project. After installing WordPress on local machine and chaning Permalinks to Post Name in admin I suddenly started getting these errors:
The requested URL was not found on this server.
Don’t you just love it when such errors appear? I forgot how I solved this in the past projects but remembered it has something to do with
.htaccess. After Googling and trying out few solutions nothing worked until I realized that with Wamp you can enable mod_rewrite via WAMPSERVER Control Panel (you will find it in your tray).
So just click on
WAMPSERVER icon, then
Apache Modules and then scroll down to
rewrite_module and enable it. Restart Apache (or restart all services) and your permalinks will work.
Seems like qTranslate is not really updated anymore or at least it is updated very slowly. So when I updated WordPress to new version I got this message and qTranslate editor in admin was disabled.
The qTranslate Editor has disabled itself because it hasn’t been tested with your WordPress version yet. This is done to prevent WordPress from malfunctioning. You can reenable it by clicking here (may cause data loss! Use at own risk!). To remove this message permanently, please update qTranslate to the corresponding version.
I guess the easiest way is to just click on the link and it will probably enable itself. I googled it and it seems some people might have problems with that. So the solution that worked for most people is this:
wp-content/plugins/qtranslate/qtranslate.php file and change line 90 from
just save it and that’s it.
Of course if WordPress is updated to new version qTranslate will disable itself again. What you can do is enable it for all version by dynamically inserting current WordPress version, like this
qTranslate will now work for all (future) versions of WordPress.
Hint: You can find out your WordPress version on the bottom right in the admin or by opening a file
/wp-includes/version.php and checking the
$wp_version variable on the top.
Note: Do this on your own risk. It seems to work for most people but beware you might loose your data if something goes wrong. The safest way is to wait for author of qTranslate to update it but it seems this is not happening.
