Backend error when clicking "Media Files"

[rhinopm]

Using Virtuemart 3.0.18 & Joomla 3.6.5

While logged in the back end as Super Administrator, everything works fine until I hit "Media Files" in Virtuemart.  It goes to a page that appears to have a css error (screenshots attached) .  I've tried un-installing and re-installing only to get the same results.  Please HALP!

This is a because a PHP error.
Change in Joomla Global config > Server > Server Settings : PHP reporting to maximum, this should display you the error.
Else you need to enable in your server PHP error reporting and check your php error.log

OK - I did those things... set error reporting to maximum - it shows no error:

Have you changed php error reporting in Joomla ?
If yes, try to find your php error.log file, it seems that you don't have enabled error display, so only way to see your bug is in this file.
In some case error.log is in your Joomla root folder or in administrator folder, in other case this can be in the log folder. If you don't find it check with your server support.

Contact onepage developer, and copy your bug report in the mail so they can fix it.
