Hello,
A server error 500 means that there was an unhandled exception while the spellcheck request was processed. The response to the Telerik.RadSpellCheckHandler.ashx request should contain the exception details. Use a HTTP debugging proxy (Fiddler for IE, Firebug for Firefox) and check the contents of the response for the spellcheck request.
Some common problems are missing or inaccessible dictionary files (*.tdf) or an invalid entry in the custom dictionary file ( [lang]-custom.txt ). In this case, you can removing the custom dictionary file to see if the problem will go away.
Greetings,
