I'm working with a new ISP who is not used to supporting WordPress. After a recent install, lots of features don't work. (Upload, plugin automatic upgrade, visual editor, permalinks.) I've traced most of the problems to what looks like a bad value for ABSPATH. With a little debugging code, I found that ABSPATH = ../ That seems wrong to me. I was expecting a full path, something like /home/xxx/public_html/.
Does anybody know what to do about this? Maybe mods to php.ini?
TIA for any clues or pointers...
