hi, i’ve seen similar issues with apc enabled on php side. on my installation nginx returned an error 5xx as well when upgrading typo3 core. may be restarting your php (or at least clearing byte-code-cache) helps. regards, chris Am 10.09.2012 um 21:14 schrieb iLinux85 [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---
