[TYPO3-dev] Upgrade from 4.5 to 4.7

[Frank Nägler]

Hi everbody,
after upgrade some installations from 4.5 to 4.7 I have now trouble on my local environment.
I am working on a mac with ZendServer (PHP 5.3.15 with Suhosin-Patch (cli) (built: Aug 24 2012 17:45:44))
After switching the source from 4.5.22 to 4.7.7 the browser shows me this error message:

Fatal error: Declaration of t3lib_cache_frontend_PhpFrontend::set() must be compatible with that of t3lib_cache_frontend_Frontend::set() in typo3_src-4.7.7/t3lib/cache/frontend/class.t3lib_cache_frontend_phpfrontend.php on line 0

I use the same source folder (same copy) on other systems, and have no problems.

Any Idea?
