I'm trying to set an icon for an item in
Sitecore 8.2. When I click the
More Icons button, I get the error message below.
The parameter is not valid. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: Parameter is not valid.
What's strange is that I have this site deployed to another environment and it's working fine there. It's only giving me this error on my local development machine. I think it might be a corrupt cached image file that's causing the error, but I don't know how to clear that cache out.
