Default Theme Dir Error

[IlyZor]

Hello,

I get this error:
"The default theme's directory is wrong, please correct it by clicking this text."

I also see no avatars.

It was defaulted to serverroot/htdocs/forum/default but I changed it to
http://www.webpage.com/forum/Themes/default after I clicked the text.

And it still won't work. I ran repair, no change.

I also checked the FTP, all files are there. The paths are correct. Still, the forum says "(warning, this path is not correct!)". I'm confused, what's wrong.

Looks like my host changed the absolute path. How can I specify the new one everywhere at once?

Take a look in the download section for repair_settings.php (or something like that).
Upload that script and run it.
But make sure you delete it afterwards.
