There seems to be many white empty pages with this Template & Virtuemart.
Both Joomla and the Template are latest versions.
We had to change the “Check out” form to “Pop Up” because the default Check Out form only produced a white page.
Putting on the Debug mode produced an error on the frontpage.

It looks like a Cache error but there is only Joomla SEO in use without caching.
Update: Looks like JoomlaWatch Agent is part of the problem. Disabling JoomlaWatch Agent gives now this error on Virtuemart Account Address editing.
