Yes, this is a very possible reason. You could use Firebug or Chrome developer tools to see if there are some errors during the loading of the page as well.
I know this is an old post but I came across it as we are seeing this behavior again. I suspected it was a Microsoft patch issue as many computers here went through the updates. A few clients are reporting the same where in the backend the background images aren't appearing and a newly created page is either created in draft mode automatically and can't be published or edited.
Good to know.
I can confirm that I had the same a couple of times but did simply reload and did not investigate further.
Since there is no response from Telerik I will open a ticket.
Let you know when I get an answer.
I am sure there are many other not reporting this but having the same issue.
Can you enable CDN Admin - Advanced - Pages - Script-something
And set front and back-end script comgining to false. Recycle and see if that fixes it. Admin - Advanced - Pages
The issue with 5.4 is MicrosoftAjax.js not being included on the initial load of the page into the editor. If you refresh, MicrosoftAjax.js gets included.
We do have an open case and will let you know if/when we get an answer.
Laura and I have the same problem. I know at least of one other person who had the same problem and solved it by enabeling CDN and setting script combining to false.
I have an ticket open as well and will report as soon as I get an answer.
We had this problem here too...(same thing seen in Markus' video). First time a page loads, no buttons, reload, buttons come back.
I removed the RadScriptManager from our masterpage and we're all good again...
That did the trick. Are you going to investigate further why this is happening?
I'll send you my bill.
Please send it with my regards to this address
