Hi
I am getting a TON (about 50 appear every 30 minutes) of general exceptions on my event viewer and I am thinking they are related to ongoing performance trouble I'm having with the system. I haven't altered my web.config file in quite a while otherwise I'd try some of the suggestions on other posts. Would anyone be willing to take a peak at my site? the errors generally follow two main themes and are the following:

Version 1:

AssemblyVersion: -1
PortalID: -1
PortalName:
UserID: -1
UserName:
ActiveTabID: -1
ActiveTabName:
RawURL:
AbsoluteURL:
AbsoluteURLReferrer:

ExceptionGUID:
InnerException: Value cannot be null. Parameter name: type
FileName:

Any help would be fantastic as I try to clean up the site and make it perform like new :)
Thanks

These typically are a result of bad data in your DesktopModules table in regards to the Supported Features for the modules installed on your site.  The easy fix is to run from Host-SQL "UPDATE {databaseOwner}{objectQualifer}DesktopModules SET SupportedFeatures = 0 WHERE SupportedFeatures = -1"

The issues has been fixed in one of the recent releases, but in older versions of DNN, if a module did not define a Business Controller Class, the installer would get confused and leave the "null" value of -1 in the SupportedFeatures Column, which ended up being translated as "Everything" instead of "Nothing" when DNN asked if your module supported features (like searching).  When DNN tries to search the module, it fails because the module doesn't actually support that.

Hope it helps,

Thanks Brian, I will try it out. Do I enter it exactly as you have typed it or do I put values in the { }'s ? It won't hurt anything right? This is awesome though, rarely are solutions so straight forward. Thanks a ton!

Mike,

You can run the SQL statement exactly as Brian has entered it from the Host -> SQL window or remove the databaseowner and objectqualifier "tokens" and run the script in Management Studio or Query Analyzer (assuming you are not using an object qualifier and your database owner is DBO -- if not you'll need to set those to match what you are using.

The idea is to only update those that are set to -1 (which is invalid) - so it certainly should not hurt anything.

Take care,

Ian
