Hello,

I am currently using Joomla 3.8.5, my PHP Version is 7.1.13, my MySQL-Version is 5.5.56.

Since the update to Joomla 3.8.4 frontend login it is not possible any more. Instead of showing a page with the K2 Users Menu there is only a completely white page with the following message:

Error: Using $this when not in object context: Using $this when not in object context

Could anyone help me with a solution to this problem, please? Backend login is working fine.

Kind regards.

Hello again,

my Provider downgraded the PHP-Version to 7.0.27. Now there is no problem any more with frontend login through the K2 Login Module.

Kind regards.

Hello,
I do not know. Where do I find this information?

Maybe a little more info:
The K2 login module on my website is not shown on the start page. Therefore after logging in, there is a redirect to the page, where the module is found.
When I had the k2 login module set to redirecting to the start page instead, the k2 user page was shown but not the k2 user menu and not the start page.

Now with PHP 7.0.27 it is working fine again with the original setting (redirecting to the page where the k2 login module is found).

The error reference is found in your error_log file.
You can ask your hosting provide to pinpoint that file. Within that file look for PHP Fatal issues.

Hello,

I had this problem again after once again updating PHP, this time to PHP 7.1.26.
But now I could find the solution. I do not know PHP, but others showed me, what to do exactly. Here it is:

In my "Debug-Call stack"-Thing it said:

Function: modK2UserHelper::getMenu()
Location: .../modules/modk2_user/helper.php:80

All I had to do was to exchange "JSite::getMenu()" with "JFactory::getApplication()->getMenu()".

Thank you very much!
