php fatal error register_question_type

Greetings bigneno,

Thank you for choosing to use this plugin! Are you receiving this error at any point while using the plugin? Are you receiving any other errors during usage?

Hi,
at any point. I had to turn it off.
I tried to add if(is_object(…)) check at the beginning, but the errors repeat multiple times in that file.
The previous version of the plugin (old name) was completely OK.

Hi,
We are having the same problem:

Greetings johsnd,

Thank you for the stack. Can you also follow the debug guidelines from the “Read This Before Posting” support post? I copied them here for your convenience. This will help me rule out common issues:

• Switch to the default theme such as Twenty Fifteen, does your problem still persist?
• De-activate all other plugins, does your problem still persist?
• If that solves the problem, re-activate your plugins one at a time and test if the problem re-appears. If so, let us know which plugin caused it.

Hey bigneno,

We haven’t heard back from you in a little while so we are going to go ahead and close the ticket. However, feel free to come back anytime and comment here if necessary. Thanks again for using our plugin.

I encounter the same issue. I run command “wp cache flush” just after installing the plugin:

When I try to login into my WordPress site i receive this error…

Fatal error: Call to a member function add() on a non-object in /home/www/aotha.com/wp-content/plugins/quiz-master-next/php/class-qmn-tracking.php on line 101

Help Please

I fixed it myself…

Manually disabled plugins then logged back in and everything worked. I was able to delete the bad plugin and back up and running.

This page helped me with the manual fix.
