Error on enabling recordings

Hello all,

i get the following error when i am trying to install the recordings module. ( Recordings (recordings) 2.2.1 setup Module)

I can not access the directory /var/lib/asterisk/sounds/custom/. Please make sure that it exists, and is writable by the web server.

i have already created the folder custom, but still get this error.

any ideas?

Thanks,

Elias
