Error 503 "Guru Méditation"

[multistud]

Hello, since the update to Joomla 5,
I have an error when I want to open a product "503 guru meditation"
and this error on all products...
I temporarily deactivated the CDN on the .fr domain
therefore, the error message is:
1267
Illegal mix of collations (utf8mb4_unicode_ci,EXPLICIT) and (utf8mb3_unicode_ci,EXPLICIT) for operation 'ifnull'.
How to solve this problem ?
VirtueMart 4.2.6 10972/Joomla 5.0.2
PHP 8.2.10 / MySQLi 8.0.35
THANKS
Kind regards, François PARTY

That looks like a 3rd party extension issue or a server issue.

1. Enable Debugging and set "Error Reporting" as "Development" in Joomla Global Configuration.
2. Set PHP Development mode for "all" in VirtueMart Configuration.

Return to the error page to see the complete error trace report. Take a screenshot of the same and post it.

It indeed looks like a server issue.

You should contact your hosting service provider to fix the issue.

I suppose that ("Error Reporting" as "Development") is at the maximum but it does not work error 503 also requires going back through FTP config to reset (Default)
PS: everything worked with VirtueMart 4.2.6 10972/Joomla 4.4.2
PHP 8.2.10 / MySQLi 8.0.35
