DNN CPU Spikes Investigation - Need Community Input    

Started By  Jane
(Topic has multiple pages1 2 )
Issue Description The site experiences consistent CPU spikes to 100 every 10 minutes. While normal CPU usage hovers around 50, these spikes cause server response times to increase up to 10 seconds. Users who access the website during these spike periods experience significant performance degradation and slow page loads.

DNN 9.11.3 - Modifying Skin .ascx files    

Started By  jacton
(Topic has multiple pages1 2 )
Hello, We recently upgraded from 9.5 to 9.11.3 and noticed when trying to modify a skin ascx file (directly on the server) that the changes weren't taking affect until incrementing the version in CRM. I don't remember having to do this in older versions. Is there a way to turn that off Thanks It makes it difficult to test skin modifications when having to increment the version after each change.

Issues with DNN Search Functionality    

Started By  AntonioG

After another page refresh, the issue seemed resolved. Ultimately, I decided to restore the site to version 9.9.0 using a previously made backup. After checking the logs, I notic...
