@Paoul33 – Yes, via FTP or the file manager from your webhost. find the folder wp-content/plugins/ delete folder for nextgen-gallery-pro. You are now able to edit your website again. install the next-gen gallery and activate it.

go to https://www.nextgen-gallery.com/ and log in to download the newest nextgen-gallery-pro.
go to your website and plugins and upload the new version of nextgen-gallery- pro. This is what I did.

Problem solved – it was not the new version 2.0.71 – that caused the problem, it was the old version of the pro pluging. ??

Where can I download version 2.0.66.37?

Me too – I can’t even log on to my site – I get this message
