I need help testing!

For some time now my plugin TestqUiz has been released to the public. Sadly, I can only solve errors that occur for situations on my server. There are so many different settings that I can't get perfect results for each one. Sometimes, those errors are important errors that really affect the plugin. Since TestqUiz doesn't seem to be much of a perfect plugin, I'm wondering if you, the community, can help me test the plugin for bugs!
