Hi,
in the same PC is running php 7.3.33 and mysql 5.7.33
in my old env xoops 2.5.10
url /modules/system/admin.php?fct=users
when I access the page you will see the list of the user registered
if I press SEARCH button I can still see the list of the users
if I type 'ceca' (for example) and press SEARCH I see in list just one user (as it should be)

in the 2 new site in 2.5.11
where one is upgraded and one is fresh installed
same page url /modules/system/admin.php?fct=users
the behavior is the same for both new site
when I access the page you will see the list of the user registered
when I press SEARCH button the list is empy
If I search for a username I always receive not found and what I typed in the field disappear

Let me know if you need more info to troubleshoot
Carlo

Thanks for letting us know.

I was able to replicate it, and I'll be looking into it, hopefully soon. I'll keep you posted.

I have the same problem (http://www.audizioni.it) after upgrading to XOOPS 2.5.11:
Fatal error: Type of SmartyCompilerException::$line must be int (as in class Exception) in /web/htdocs/www.audizioni.it/home/site/class/libraries/vendor/smarty/smarty/libs/sysplugins/smartycompilerexception.php on line 8

This should be fixed with this commit:

Try to make the same changes in your installation and let us know if it worked.

Hi,
sorry for the late reply,
yes it working for my installation
regards
Carlo

Terrific, I'm happy to hear that it's working!
