Hello everyone,

(For almost 2 years we have piwigo up and running and its a good environment for a growing foto collection. Happy with it until the major upgrade to 11.0.x When i want to edit the groups for users i get a Fatal error:
<b>Fatal error</b>:  Uncaught Error: Using $this when not in object context in /var/www/html/xxxxxx-beeldbank/include/smarty/libs/sysplugins/smarty_internal_debug.php:200
Stack trace:
#0 /var/www/html/xxxxxx-beeldbank/include/template.class.php(571): Smarty_Internal_Debug::display_debug()
#1 /var/www/html/xxxxxx-beeldbank/include/page_tail.php(94): Template-&gt;p()
#2 /var/www/html/xxxxxx-beeldbank/admin.php(317): include('/var/www/html/c...')
#3 {main}
  thrown in <b>/var/www/html/xxxxxx-beeldbank/include/smarty/libs/sysplugins/smarty_internal_debug.php</b> on line <b>200</b><br />

This is looking like a bug. I dont see a possibility to report this)
