HTML module scrolls up and out of window during editing Started By Tom Melkonian Hi, We're seeing this issue which is frustrating for users: When editing inside an HTML module (not in source mode) , when a user used a Return to add a new line, the Editor window scrools up and off-screen and the user is unable to continue editing. This is occurring on some pages and not others, I believe it might be related to how much content there is in the vertical space on the page (longer pages seem to show this issue. Has anyone else seen this issue and know how to fix I've se...	2	123	0	3/6/2026 3:40 PM by Tom Melkonian

Slow asset upload Started By shov I am a DNN content manager using Evoq Basic 9.10. I have been dealing with slow asset uploads since the 9.10 upgrade. 1-2 files will upload at normal speed from the frontend GUI, but any more tend to fail or hang for minutes until finally completing the upload. It will generally take minutes to upload Editing or saving pages is generally as challenging. Every time I navigate to Assets or Pages, this progress bar appears, hangs for several minutes, then loads the content. The behavi...	1	237	0	12/15/2025 2:52 PM by shov
Cloudflare Only Caching ~11% for My DNN 10.1.2 Site — Looking for Advice Started By D0rk52 Hi everyone, I’m trying to optimize Cloudflare caching for my DNN 10.1.2 website, azmanagedit.com, but I’m noticing that Cloudflare is only caching about 11 of all requests. For reference, here are my last 24-hour stats: Unique Visitors: 1.7k Total Requests: 28.4k Percent Cached: 11.23 Total Data Served: 569 MB Data Cached: 64 MB This seems very low compared to what I’d expect, even for a dynamic CMS like DNN. I’m trying to understand what might be preventing Cloudflare f...	1	179	1	12/11/2025 4:20 PM by D0rk52

DNN CPU Spikes Investigation - Need Community Input Started By Jane 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. Although not all users are affected (depending on their timing of access), the impact on user experience during these spikes is substantial. This pattern seems indicative...	12	1204	3	11/28/2024 8:17 AM by Jane
DNN 9.11.3 - Modifying Skin .ascx files Started By jacton 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.	15	1143	4	7/8/2024 11:32 AM by jacton
