Oh boy, now mine is doing this again. I fixed it for my last domain but the same steps aren't working for my new one. My definitions are correct and I replaced the two files. When I try to add an area to CMS with PowerCMS I get that error and it creates the _mmServerScripts folder but nothing is in it. I also deleted the configuration file and all of that "normal" stuff. If I place the missing files in the folder myself, it deletes it again.
