Somehow erased all hosted website files

[rt_bower]

I need help in understanding how emptying the trash cans in ISPConfig (V 2.2.32) somehow caused all the sites hosted on my server to be reinitialized back to a default folder without a single warning. All files were erased from about two dozen commercially hosted sites. I'm ready to provide any further detail you request. The log file is about 10M or I would have attached it. I would especially appreciate hearing from Falko or Till. Don't get me wrong, I backup every night and was able to restore it all in about an hour; but, I need to understand what went wrong to continue considering ISPConfig a viable option.

Thanks, Rt_bower
