After manual update to 13.05 access forbidden

Support intro

After an update from 13.04 to 13.05, i get an access forbidden on my startscreen. At first it ried the gui-update, whiche worked befoer every time(i use it since version 12.0). After the broken update, i start the manual way (https://docs.nextcloud.com/server/13/admin_manual/maintenance/manual_upgrade.html). I do not get any error on this way, but by using cloud.leichtwind.de i get a access forbidden.

Nextcloud version (eg, 12.0.2): 13.05
Operating system and version (eg, Ubuntu 17.04): 17.04
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4 behind nginx
PHP version (eg, 7.1): 7.2

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Y
