Detailed Description of the issue:

After updating from ARVE 6.5.0 to 7.5.1 and ARVE Pro from 1.6.4. to 2.5.1 the page with the video on does not display anything but the headline. Also the admin toolbar does not display. I use a twenty-fifteen child theme and I have the same issue with the twenty-fifteen wordpress standard theme. I also de-activated all other plugins but the result is the same.

What you are expecting?
The page with the video on with the admin toolbar.

and what you are seeing instead?
Just the page header and the headline.

If you revert back then I can not debug your problem, also your current site is not working even with old version, the JavaScript triggers on the play buttons are missing, when I click a video thumbnail nothing happens.

There may be a caching issue, try deleting your cache.

I see it. There was a bunch of updates, one of them probably caused this situation. I am now reverting to before all the uptades and I’ll do the updates one by one and re-check. If I find the culprit this way I will then do the ARVE updates again and see what happens next.

Now I have reverted the site to before the updates and deactivated all plugins. It worked as before. Then I have installed shortcake and done the updateds of ARVE and ARVE PRO. The video pages are broken, all I see is the site header and the headline. As this is my business site I can’t leave it like this. I wil now revert ARVE and ARVE pro and activate all the outdated plugins. Then I will update the other plugins one by one to see where the javascript error with the video player comes from.

Now all the plugins I need are back on and updated, except for ARVE and ARVE pro which are reverted. The videos are playable now. Unfortunately I don’t know which was the culprit, it may have been as you said a caching problem. Could the php version I use be a problem?
