I use the Free version about a half year and I am pretty satisfied with it, so
I ordered the PRO Version recently, because I wanted to upload Pictures from my Facebook Account,
but I can’t get it to Work.
The PRO-Version installed just fine.
-> I use the german translation.
I created a new gallery, clicked on “add Pictures” and then “Import of your Facebook Account”
After that I see this:
if I click on “Mit Facebook einloggen” (log in to Facebook) I get the Error message:
“Bad request: Authentication verifier does not exists”
and a pretty scrambled URL in my Browser.
