The Service is unavailable after login      

Started By  Malcolm Bradley
Any help would be appreciated with this weird one.  The site displays correctly until after login when my browser goes blank with the simple message The service is unavailable is displayed.  I clear my cache or open a new browser window and the site (not logged in) reappears as if nothing has happened. I have tried restoring to an earlier time but nothing appears to correct the issue. As earlier - any help gratefully received!

HTML Module Content in Edit Mode Doesn't Match Live and Vice Versa      

Started By  H. Hugh-Jones
Hello all, We side-graded from DNN Evoq to Platform Edition 9.10.2 a few months ago, and recently we have noticed issues between edit mode and live (non-edit) mode in HTML modules. Sometimes after we publish updated HTML module content, the updated content is visible only in edit mode and the old content continues to display in live mode. Sometimes this updated content is only visible in live mode and the old content continues to display when we go into edit mode. We don't have this proble...

Google Page Speed Insights      

Started By  RogerGoodwin
Hi, I am looking at ways to create a new base DNN site which has a reasonable page speed score out of the box based on the mobile results. I have managed to get the desktop to have a performance of 94/100 but the mobile I am struggling to get anything over about 60. The issues typically relate to render blocking resources, FCP and LCP. Has anyone got any suggestions on how to resolve these issues or are there any plans to help improve the core DNN build. Thanks Roger

I am not going to use messaging, etc - just going to be a custom ecommerce site.  I can give you the url if anyone wants to see it to monitor the requests.  It is not h...

Please check your internet connection      

Started By  willem
