Thread:Project:Support desk/500 error when uploading/viewing images/reply (2)

I was able to figure out what the problem was. The problem in my case was related to how IIS was configured for FastCGI. In the FastCGI settings section of IIS I noticed that the Max Instances was set to 0. I increased the value to 4 and it worked. I'll need to adjust this setting more to find the sweet spot.
