[Wed May 27 11:43:12 2015] [error] [client 80.152.XXX.XXX] client denied by server configuration: /var/www/vhosts/dev.xxx.eu/fibu/application/modules/quotes/views/view.php
EDIT: Also I’m getting the following error as response to the 500 Error in Console:
Unable to load the requested language file: language/German/form_validation_lang.php
But there is no form_validation_lang file. Neither in this version nor in the current one.
EDIT 2: In application/config.php on line 72 I had “German” as value, which doesn’t seem to work, because in system/language is no folder for German. Set this back to default and it works.
