"500 - Internal server error" on Linux virtual server through GoDaddy

I have a Linux virtual server hosted with GoDaddy and it's out of disk space. i'm getting 500-Internal server error when trying to load Plesk control panel.  it's not the web sites taking up disk space, it's logs or temp files or something.

Does anyone know what files can be removed safely?  I'm not a Linux wiz, so any help would be appreciated. Thanks!

NVM,  I figured it out... one of the websites had 13 GB of log files.  All good!
