The active theme is damaged, the default theme is used
Hello
I tried to install Classipress, when I upload the zip file I do get the message succesfully installed, but when I click on activate
I get the message active theme is damaged, the default theme is used.
So I dropped all the database tables that were created by Wordpress and I deleted all files.
I reinstalled Wordpress, that simply worked the way it should work. But with trying to activate Classipress I get the above error message and swicthes to the twenty-ten theme.
I use(d) a Dutch version of Wordpress, can that be the problem, or must I look somewhere else to find the problem?
