We've noticed a trend of random errors using this plugin and it would be great if we could get some direction on fixing these.
The first error we are randomly seeing is that when a person completes a single/multiple choice question quiz, they're greeted with the following error
"Error - no questions Quitting."
Obviously this is not the case since they've spent the time to take the quiz and answered the questions.
The other error we've been seeing randomly is:
"PHP Sessions error. Check your sessions settings."
To attempt to correct this, we've increased session timeouts as well as ensuring the sessions directory is set correctly in php.ini. When this error shows up for people taking the test, the results page shows:
"Warning: Division by zero in /home/username/public_html/wp-content/plugins/wp-survey-and-quiz-tool/pages/admin/results/mark.php on line 122"
We've made sure to update all software including this plugin to try to resolve these issues however, they continue to randomly appear with no true pattern at all.
Any assistance and or suggestions to stop this from happening would be greatly appreciated.
