phpBB error: Could not get style data

[mister_v]

Hello,

I restored a backup of my forum (phpBB).
Put no I get the follwong error:

General Error
Could not get style data

As far as I know the backup has all the files, including those of styles.
Anyone got any ideas

I had the same problem once.
Delete the contents of the folder cache/; except index.html and .htaccess.

Make also sure the folder is writable by apache (or whatever user you webserver has),
Same for the folder store/.
