Hello
I'm testing a site migration fron J! 2.5.22 to 3.3.1

I get this error in administration:

Notice: Use of undefined constant K2_JVERSION - assumed 'K2_JVERSION' in /var/www/vhosts/studiocornacchia.eu/antonio/mmp_upgrade/administrator/modules/mod_k2_stats/mod_k2_stats.php on line 15 Notice: Use of undefined constant K2_JVERSION - assumed 'K2_JVERSION' in /var/www/vhosts/studiocornacchia.eu/antonio/mmp_upgrade/administrator/modules/mod_k2_stats/mod_k2_stats.php on line 23 Notice: Use of undefined constant K2_JVERSION - assumed 'K2_JVERSION' in /var/www/vhosts/studiocornacchia.eu/antonio/mmp_upgrade/administrator/modules/mod_k2_stats/helper.php on line 23 Notice: Use of undefined constant K2_JVERSION - assumed 'K2_JVERSION' in /var/www/vhosts/studiocornacchia.eu/antonio/mmp_upgrade/administrator/modules/mod_k2_stats/tmpl/default.php on line 15 Notice: Use of undefined constant K2_JVERSION - assumed 'K2_JVERSION' in /var/www/vhosts/studiocornacchia.eu/antonio/mmp_upgrade/administrator/modules/mod_k2_stats/tmpl/default.php on line 32 Fatal error: Class 'JPane' not found in /var/www/vhosts/studiocornacchia.eu/antonio/mmp_upgrade/administrator/modules/mod_k2_stats/tmpl/default.php on line 32


I tried to reinstall the component, but the error is there again.
Can you help me to fix it?

Hi. Ensure that you are using the latest version of K2 and that the K2 system plugin is installed and enabled.

Thanks for reply. I reinstalled two times the latest K2 and the plugins are enabled.

This seems to be a notice not an error.

Have you tried going to joomla / Global Configuration / Server / Error Reporting
System Default and change it to None ?

Ok, with System Default it doesn't appear.
Is it not important indeed?

I think its not but you should get an opinion from a dev just to be sure.

In any case on a live site you shouldn't display notifications like these so you should leave Error Reporting to none (if its a live server)

@theant

In live sites it is always recommended to set error reporting to "None" . As i can see in your message the notices are coming from the K2 statistics module so it is not going to affect your site probably.
