We have just upgraded to Kentico Hotfix 11.0.49 and are having problems, when loading a CMS page or a library tab, the console will repeatedly output.
Failed to load resource: the server responded with a status of 404 (Not Found) GetResource.ashx:1
but eventually, the CMS or selected tab will load but only after a certain period of time from a few seconds to even minutes.
As for the media library, the tab content won't load right away, and if I click on another tab like "General" this happens
Uncaught Reference Error: Tabs is not defined at SelTab at HTMLLIElement.onclick
Lastly, when the media library finally does load the names are truncated. https://imgur.com/a/JbRuKCy
I've tried clearing the cache through Chrome's settings, as well as checking "Disable Cache" in Chrome Dev Tools.
This is most likely a javascript issue. If there were javascript updates for the media library, then your best solution is to clear the browser cache and refresh the page so it grabs the most recent, uncached version of javascript.
I've tried clearing the cache through Chrome's settings, as well as checking "Disable Cache" in Chrome Dev Tools and wasn't able to get any difference in whats happening.
Kentico utilizes iFrames very heavily, so you may need to click within the iframe in the center of the UI (to the right of the content tree) and refresh the frame from there. 99% of these issues are due to javascript caching after an upgrade or hotfix.
What were the upgrade steps and actions you made? Were the Upgrade Start and Finish events logged in the Event log? And no errors between them?
Heya Robert, I would check the CMS directories for .old/.new JS files.
If your project made modifications to the kentico JS, the hotfix might be waiting for you to resolve the conflict.
