Thread:Extension talk:ParserFunctions/on install: Unable to move the new CDB file into place

On running the installed extension I get: Unable to move the new CDB file into place.

As I understand I should have 777 rights on the cache subdir. changing that still genertes the error. any help is appreciated.
