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?

I don’t have SimpleGallery installed on this DotNetNuke instance. That’s why I don’t understand why these errors are happening.
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)?
(www.mysite.com/DesktopModules/SimpleGallery/RSS.aspx)
Found it. The error message gave me the idea that it was the website who generate the error and not a bot or something else outside the website. After searching the iis logs I found that it was a other DNN instance on my server. One of the inactive portals (not active in IIS) was looking for the RSS.aspx and generating lots of errors.
