[Resolved] Error 500 after latest update wordpress 6.3

While one of my teammates takes care of your ticket, I will provide you with the first debugging steps.

The blank page means (or “500 error”) that there is an error in the PHP code that your site runs. When errors are not caught, the server stops everything and returns a page that says “500 error” or an empty page. Different servers are configured to display these errors slightly differently, but they all mean the same – there is an unhandled PHP error in the site’s code.

First, you need to see what the errors are. Guessing what might be the problem and trying different solutions may lead to even more trouble. The first step is to enable debug. You can do this by adding a few lines to the site’s wp-config.php file. With error log enabled, you will see what the actual problem is.

To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

In order to enable the error logging to a file on the server you need to add yet one more similar line:

define( 'WP_DEBUG_LOG', true );

In this case, the errors will be saved to a debug.log log file inside the /wp-content/directory.

Let us know what you see after the debug mode has been enabled.

The problem is due to memory and it's not happening with WPML but with Divi and many plugins (WooCommerce related).

The error is happening ebcause these plugins are creating a lot of issues, repeatedly and they end up exhausting the memory.

I think that those plugins are not compatible with WP 6.3 then.

Please watch this video because i can see i didn't explain well enough.

I was not saying that you didn't have enough memory, but that basically all your plugins are NOT working correctly because of PHP issues (probably due to php 8.2 which is way too new for WordPress.) and when another plugin comes and touches something that is already not workng correctly, it makes it crash.

Right now the errors you're seeing is because your site ends up without memory because of all the issues you have.

I suspect that downgrading your PHP version to version 8.0 will at least take care of most of the issues on your site and prevent the memory exhaustion problem. if the problem keeps happening then, we will see different errors on the debug.log that will give us a clue about what's happening.

Make sure you keep the debug.log enabled. rename the current file after you have downgraded your PHP version, that way we can have a shorter list of issues which you can send to me again as you did before.

The video is this one: hidden link, sorry about that!

At this point, would it be possible to have access to your site and FTP access as well so i can investigate better what's going on?

If the site is a production one, then may i suggest you clone the site to one of our servers so we can work risk-free on your end? i'm saying this because there's a chance i have to enable the String Translations Plugin and it would crash the site.

Regards.
