We have a DNN 5.6.x installation where one Portal is continually throwing the following error:
------------------------------------------------------------------
DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider
ExceptionGUID: 07f03b2a-49dd-4129-9297-f7a52f804232
InnerException: Index was outside the bounds of the array.
FileName:

FileColumnNumber: 0
Method: System.Collections.Generic.Dictionary`2.Insert
StackTrace:
Message: System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at System.Collections.Generic.Dictionary`2.set_Item(TKey key, TValue value) at DotNetNuke.Services.Localization.Localization.GetResourceFileCallBack(CacheItemArgs cacheItemArgs) at DotNetNuke.Common.Utilities.DataCache.GetCachedDataFromDictionary(CacheItemArgs cacheItemArgs, CacheItemExpiredCallback cacheItemExpired)
------------------------------------------------------------------
None of the other portals are showing this error. Apparently it's happening with each page load. All the postings I see for this error have to do with DNN 4.x, so I'm not sure where to start debugging this issue.
We were scheduling a service patch this weekend, but need to resolve this issue first. Our test environment, while a bit older on the data is the same version of DNN and same config - doesn't appear to have this issue.
Could have the client (portal admin) done something to cause this?
