Question

Where does IIS 7.5 log errors?

Event Viewer? Log File?

I get a very non specific internal 500 error. I would like to find out more.

I\'m running PHP

Answer 1

I once had a problem where the error log wasn't writeable by php. I added the IUSR user to the file's security permissions (right-click the file, properties, security tab) with read write and modify permissions and was then able to see php errors in the log file.
