    I get lots of the following errors. It’s on DNN 9.2.0 In the past I used SimpleGallery but not anymore. Did a search in the files and database but nowhere SimpleGallery is found. Any ideas where this error comes from?  


    DefaultDataProvider:DotNetNuke.Data.SqlDataProvider, DotNetNuke










    Message:Unhandled Error:


    InnerMessage:The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

        I don’t have SimpleGallery installed on this DotNetNuke instance. That’s why I don’t understand why these errors are happening.

          Because the error refers to RSS.aspx, I'd guess that this has something to do with RSS.

          If you uninstalled the module (Look at the Extensions Persona Bar to verify that the module really is installed.) then there might be a left over scheduled task that handles the RSS feed.

          You should also check the bin folder and eliminate any files related to the Simple Gallery module.

            Aslo I have seen bots trying to acces the RSS feed of an uninstalled module for a long time.
            You could try the path directly and see what happens (to see if these are actual calls or maybe a scheduled Task as Joe suggested)?
