Hello everybody

I have a problem with a dotnetnuke portal. Each time I click on a module's settings (being logged in as admin ) I get an error. I put below the log created from this error

Where and what should I check in order to solve this problem?

ModuleId: 568
ModuleDefId: -1

ModuleControlSource: Admin/Modules/ModuleSettings.ascx

InnerException: Object reference not set to an instance of an object.

StackTrace:

I really don't understad what is causing the error.

Any help appreciated.

Thank you in advance,
Tomas

this looks like there is either an issue with the structure of your moduleSettings (or TabmoduleSettings) table or content inside of it. Please validate the 2 tables of your database.
