Asterisk Issue - Cannot write to sip.conf, retrieve sip.conf in 0810

I just reinstalled 0810 on my core, and I tried to setup my phone lines. I used the webadmin to input the voip settings using the sipgate hack because my provider isn't on the list. I went to FreePBX to see if it took and to change the sip.conf a little, and it gives me those two errors. When I try to manually apply configuration changes, I get this error log:

Anything I can do at this point? Looks like permissions, but I am not for sure. This didn't happen last time I installed, a little over a week ago.
