Hi, I just installed Yaf from my hosting provider godaddy.com website. Installation is successfully complete and the database created. When I try to open either mysite/forum/install or mysite/forum/, I am getting the same:
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
The installation was fully automated, I didn't need to copy any files. All configs seem to be ok. What can be the problem? Thank you

If you're in internet explorer you need to go to Tools -> Internet Options -> Advanced Tab -> Uncheck "Show friendly HTTP error messages".

This will provide you with details about the error. Post those details here.
