I found (for me ) a problem.
I create 2 or more users and I want to create 2 site's with 2 blogs wordpress.
User1 - example.com -> Database Name: "blog".
User2 - example1.com -> Database Name: "blog" doesn't work, must be different.
I guess this problem it is because when mysql create databases, din't create something like: name_blog, or userID_blog, or domain_blog.
Is that ok ?
I forgot. I have version I-MSCP v1.1.18
