Hi,
Please, see the following forum thread on the subject:
Cannot read the configuration/dictionary language parameters!.
This exception would occur in a scenario when the spell window performs a postback, sending the text to be spellchecked to the server. On the server, the
SpellCheckHandler HTTP handler tries to read information about the language to be used for spellchecking and some additional information from the POST array.
For some unknown reason (we are not sure which) this information is missing.
One possibility is to use Fiddler and/or FireBug to examine the information in the Request object when the Spell Dialog makes the request. Perhaps the information there can provide some clues why the
DictionaryLanguage or
Configuration POST variables are empty.
There could be something in your Web.config or your application setup that messes things up.
In case you are not able to resolve the issue, we ask you to send us a simple project that reproduces the problem - then we will find out what is causing it.
All the best,
Rumen
