I have 12 sites.
Usually I am able to handle these kind of errors inside database/software (I am working with php/mysql since 1996). But IspConfig uses complex tree logic, I will not be able to "crack" it quickly. Since I do not understand logic I can not touch database. This is why I asked for help. If I could manage it myself, I would not bother others
But I really need help.
I do not blame IspConfig code at all, I just need to fix the problem. As to changing hosting panel - this is my last option, only possible if I cannot fix this problem in a reasonable time.
IspConfig is really good but currently it generates ServerAlias in a such way that shows one site instead of another. I already changed this manually five times today in apache files...
