Hi there,

I am getting this message on two of my pages:

https://thelanguagesherpa.com/russian-guide/
https://thelanguagesherpa.com/spanish-guide/

Can you please tell me how to fix this?

Best,
LS

Hey LS,

There are a lot of factors that could cause that error. Below is a list of solutions. Please try them all.

  1. Testing For Theme Related Issue
  2. Testing For Plugin Conflict
  3. Theme Update
  4. Child Theme
  5. Css/Js Customization
  6. Increasing Php Memory Limit
  7. Disabling Cache
  8. Disabling Cdn
  9. Permalinks
  10. Version Compatibility

If none of that helps, the problem is most probably with your web host. If this is the case, please contact your web host.

Thanks.

Hi Christian,

Thank you for your response. I actually saw a thread in which the user was experiencing a similar problem, so I preemptively went through all of the possible factors that you listed. However, I wasn’t able to identify the source of the problem.

I have also contacted my web host, and they cannot see what the problem is either.

Hi LS,

I would request you to add the below-given code into your wp-config.php file for debug setup, and the error logged into the file name debug.log inside the wp-content folder.
You can let us know if you find any error that is related to our theme or theme bundled plugins. We can do further investigation based on that.

// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );

// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );

// Disable display of errors and warnings 
define( 'WP_DEBUG_DISPLAY', false );
//SET PHP INI DISPLAY ERROR FALSE
@ini_set( 'display_errors', 0 );

Please find the video that will help you to edit wp-config.php and add the above code : https://www.youtube.com/watch?v=3SDPTafEM8o

Thanks

Hi Tristup,

I’m sorry but the tutorial you’ve sent me is very unclear, and I don’t want to do any permanent damage, messing around with something I don’t understand.

Can I kindly request that you have a look if I leave a secure note?

Many thanks

Hi LS,

It mostly happens due to the broken HTML which is been added within the content. I would suggest you check by deleting the section one by one till the issue is fixed, and the last one you have deleted before the fix is the actual issue.
If that does not helps, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site.
And give us access in the secure note including:

– WordPress Site URL & Login URL
– WordPress Admin username/password

To create a secure note, click the key icon underneath any of your posts.

Hi Tristup,

I had a go at gradually deleting the sections one by one, but either I didn’t do it correctly or it didn’t work, because I didn’t see any difference.

I have copied my site to a staging server and will attach a secure note below.

Just for your information, the pages exhbiting these errors are:

Hello Thomas,

You are having an issue because you have installed the Pagination by BestWebSoft plugin. Be advised that pages or post created with the Pro Editor does not support pagination. You may need to disable the Pagination for the pages in Pagination > Settings > General.

Kindly let us know how it goes.

#9

Hi Ruenel,

Thank you for your help. I have disabled pagination and have wiped caches, but there still seem to be errors on the pages.

E.g. on https://thelanguagesherpa.com/russian-guide/3/ there is still an error

Hi LS,

It appears the cause might be because it was updated from very old versions to the latest, since there is a big gap with the features, it caused internal errors. Unfortunately, we don’t know the exact error unless we can see the error log. Still, we can’t promise any fix if this is related to deprecated features and we can only recommend re-creating the affected pages or custom codes. The live page only appears working because of the cache, although you said the cache is already cleared, I can still confirm that the resources are served from CDN in which served the caches and it’s based on browser network logs and its source code.
If you can provide FTP login credentials, then we can help to point out the cause but we may not able to provide a solution.

NOTE: I have checked your staging server, but unfortunately it shows the Critical Error page.

Thanks

Hi Tristup,

Thank you for your continued help.

I have attached my FTP login credentials in a secure note below.

Hello @riugn557,

The issue is coming from the Google Analytics plugin. I went ahead deactivated the plugin. The issue is now resolved. You should now be able to log in.

Check your site now.

#13

Hi Ruenel,

Thank you for your help.

I am slightly confused - I logged into my live site (details in secure note below), and have checked that both the Google Analytics plugin and the Pagination plugin have been deactivated. I have cleared all of the caches, but I am still getting the same error message.

#14

Hello @riugn557,

Please clear all your plugin caches or at least temporarily disable the caching and optimizing plugins while you are troubleshooting.

Hi Ruenel,

I have purged all of the caches but I am still getting the errors

#16

Hey LS,

Your case is a 3rd party plugin conflict. I’ve deactivated all 3rd party plugins in your site in your pages are fixed. Please activate the 3rd party plugins ONE BY ONE to see which one is causing the issue. Please report to the plugin developer once you’ve found the conflicting plugin.

Thanks.

#17

Hi Christian,

I played around with the plugins a bit more and I found the opposite of what you did - i.e. the problem was not caused by a third-party plugin, but by the The Grid plugin.

I have now turned all other relevant plugins back on and the website is working fine. As soon as I turn on The Grid, the pages I highlighted above crash.

Could you please help me find a solution, as I have a section on these pages which uses The Grid.

Thank you,
LS

#18

Hi @riugn557,

I tried to activate your The Grid Plugin in your live website and I can confirm there’s an error. The error is about the Allowed memory size bytes exhausted. To fix your issue, I increase the WP_MEMORY_LIMIT in your wp-config.php from 512M to 1024M and it fix your issue.

Hope that helps.

Thank you.
