Thanks for a quick answer, nice plugin and a perfect solution.
Hi
If I update with a new image, it’s still the same problem: https://j-fr.dk//thumbs/thumbs_1975-Island-Siglufjordur-57-03.jpg
Just made another album and gets the same error.
And yes we do have the Pro version of the plugin.
It has nothing to do with the hosting.
I block all ip numbers by default in the htaccess file, and then I open for a few to be able to control who has access to the site.
So to be more specific about my request. Could you tell me the address you connect to if you select dropbox backup, so I can open for this host name or ip address?
