What happened?

Hello everyone,

After upgrading 2 separate DNN sites to V10.0.1 we are getting runtime errors for all of our custom modules that follow the same pattern below where the name of the module appears in the error message:

[ERROR] DotNetNuke.Services.Exceptions.Exceptions - System.Exception: Error Creating BusinessControllerClass '' of module() id=(484) in tab(40) and portal(0) ---> System.ArgumentException: Argument cannot be null or an empty string
Parameter name: CacheKey
at DotNetNuke.Services.Cache.CachingProvider.GetCacheKey(String cacheKey)
at DotNetNuke.Common.Utilities.DataCache.GetCache(String cacheKey)
at DotNetNuke.Framework.Reflection.CreateType(String typeName, String cacheKey, Boolean useCache, Boolean ignoreErrors)
at DotNetNuke.Services.Search.ModuleIndexer.GetModulesForIndex(Int32 portalId)

Any hints as to what might be the cause and how to solve?

Thank you!
Ben DiMolfetta

check the table DesktopModules and make sure your module does not have -1 as the value for SupportedFeatures, if it does, try changing the value to 0.

Thank you michael-lorenz that worked!

Now seeing a long list of these errors:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
at System.Web.UI.ControlCollection.Add(Control child)

Any thoughts here as well? Appreciate the guidance!
