Hello Everyone,


(Running piwigo for a couple of years whitout any problem but after the update  from 2.x.x. thera are problems with the managing of user groups. In the latest version before there was no problem at all: this is the error message: <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 />

How can I solve this problem because I dont see how. Detail is that managing of the user groups is working from the android piwigo app)
