I signed up for the 2.0 Beta release, and downloaded simple_lightbox_master from Github.
I uploaded it, deactivated version and activated the plugin. None of my pictures have the lightbox functionality anymore, so I had to revert back to the old version.
Is there something I had to do in order to make this work? There were no readme instructions on how to upgrade to 2.0 Beta.
Any help would be appreciated!
