There has been a critical error on this website. Please check your site admin em

ah ok well I found a workaround :

I disabled a rule in rankmath via cloudflare ip source address user agent  and in coding  for rankmath timeout at the same time i downgraded wordpress to 6.2.2  by manually deleting all wordpress core files and uploading 6.2.2

now the conflict is not there 

and the error log is not large I cleared it out 

but I was getting this in error_log  below but now the conflict is away

I believe The issue has to do with something new in WordPress 6.3 It has created lots of problems. Me and my business partner manage over 100 sites and half of them or more have problems. Backend wp-admin critical error, or 503 error or 500 error. Front end works fine.

I can confirm the first problem was with 
1. Google Site Kit - they are still working on a fix in but not yet
2. Rank Math - still trying to analyze it 
3. WPML Multilingual CMS (Core)  Version 4.6.5 - this has been updated but possibly still has conflict because
4. WPML String Translation Version 3.2.7 when activated with your plugin / and or Google Site Kit throws errors only in backend - 
5. Also multiple plugins are throwing php errors under the latest wordpress verison  for example Max Mega Menu Version 3.2.2 

I can confirm downgrading to PHP 8.0 or upgrading from 8.1 to 8.2 does not solve the problem.  Many sites can't go below 8.0 because so many themes, plugins, etc have been updated to work with PHP 8.0 and higher.  

I can confirm the only workarounds are:
1.  Disable Rank Math Plugin and Google Site Kit so that WPML throws no errors  -OR-
2.  Downgrade WordPress to Version 6.2.2  then re-enable Rank Math and Google Site Kit

More information:
On the primary website I am writing this issue about we disabled all plugins except only necessary one at a time to see where he conflict lies.

Themes installed on this site and others*:
VanTam Themes, Ocean WP, Traveler, GeneratePress, Divi, BeTheme, The 7 *I won't list all because it is not a theme problem

Basic required plugins:
Bulletproof Security
Wordfence
Woocommerce
Woocommerce Shipping & Tax
Fish & Ships
Perfmatters
Rank Math SEO
Google Site Kit
WPML Multilingual CMS 
WPML String Translation
UpdraftPlus
WPML Forms Multilingual

in some cases:
Shoplentor
YITH extras for Woocommerce

and in some cases required plugins for the theme

How tested:
Only activated the two WPML Plugins then the offending plugin (ie Rank math or Google Site Kit) both caused the backend to crash with errors

We have cleaned out manually all folders except what is needed, re-uploaded WordPress 6.2.2 manually via FTP, deleted and re-downloaded each and every plugin only the two workarounds stop the odd behavior until WordPress and other Plugin authors find the bugs and correct them.

I hope this helps you

Thanks for sharing your insights @startechmarketing. It’s not uncommon to encounter PHP 8 related warnings or errors with the latest version of WordPress and some plugins. Many such warnings are deprecation notices and don’t impact any functionality with regards the Site Kit related ones, as per the GitHub issue shared.

I’ll let you know once that GitHub issue is addressed. For any other plugins, you can reach out in their support forums. You’ll also find an update on WordPress support for the latest versions of PHP 8 here.

I have a response from WPML it may help you, I just updated my wordpress support thread dealing with the excessive memory leaks in version 6.3

Dear WordPress Support:

I have an update from WPML
They found that when string translation is activated they get a following error: Allowed memory size of 536870912 bytes exhausted

Increasing memory to 2048 issue persists

They say many users are reporting performance issues with WordPress 6.3

He say it is in regard to how many string translations you would have on the website. They will try deleting strings that are not used but this is complicated. I can’t imagine even heavy performing sites using up more than 2048 memory in a server. So I expect that Rank Math and Google Site Kit also is adding to the fuel of memory usage in something you did in you latest version.

Please let me know so I can communicate back to the other plugin developers we are downgraded for the moment until you fix your memory leak

Thanks

Thanks for the update @startechmarketing. I suspect there isn’t be much we can do with regards removing string translations given we do aim to allow users to use Site Kit in their own locale. I’ll will, however, pass on your feedback. Thank you!

Your welcome, sure but I think the memory leak is the big problem I will share this thread with WPML maybe they can tell me why the leak ? We only deleted 4 string translations which is small to make a big leak like this. Unless it is looping or something.

If you’re referring to memory leaks with WordPress 6.3 in general, I would suggest gathering more information and using the fixing WordPress forums. We’re limited to Site Kit support queries here in the support forums, and I don’t want to give you any wrong information about WordPress in general where it’s not my expertise. I do appreciate you sharing your findings however.

If you can determine any issue attributed to Site Kit specifically, other than the amount of translatable strings, let me know and I’d be happy to help. As mentioned, I will keep you updated once we have an update on https://github.com/google/site-kit-wp/issues/7147.

Thanks James,

I have already reported in the WordPress forums, I spend a lot of money and time finding the error. I know your plugin also exhaust resources because when I activate WPML plugin and your deactivated not a problem moment I activate yours (or rank math’s) then the memory problem critical error happens. I am not spending more time on this issue, but you must have an issue with WordPress 6.3 I don’t know how give you what you need I hope you will locate it or better WordPress fix what they did.

Just to let you know that there is a?fix out?for the deprecation notice you previously reported. Thanks again for reporting this. If you run into any further issues, be sure to reach out.

Thanks that means when I update the plugin, it will correct ?

That’s correct with regards the deprecation notices @startechmarketing! Thanks for reporting this.
