I just installed q2a on my web server. (version 1.6.3)
There's no questions written (it's totally initial state right after installation)
It had worked with no problem until I installed Badge plugin.
But Internal Error - 500 occurs if I activate Badge plugin.
Once it occurs, there's no page available.
It comes back after deleting Badge plugin folder. (But if I recover badge plugin folder, it occurs error again)
So, I deleted badge related data from qa_option table. And I dropped qa_achievements table (It doesn't how errors even if I recover badge plugin folder)
But, I really want to activate Badge plugin. How can I solve this problem?
