This is a website that we took over for another hosting company and I have no experience with MojoPortal. The site is running version 2.3.4.2 and .NET 4.0.
We are getting this error when editing page content:
"We're sorry but a server error has occurred while trying to process your request."
This is what I am seeing in the error log:
