@nymills i downloaded a database backup, and saw that indeed, because the site was set up and tested in a different location first, some entries in the database referred to the old location. I edited those entries to point to the new location (deleted the old database and uploaded the edited version) and then also used the FAQ instructions to change the settings.
It is a bit complicated but thankfully it worked for me 🙂
Having the same problem here too with the lightbox.
Using Firefox 25.0.1 on a Mac it works fine, but on every other browser (including Safari on an iPad running iOS 7.0.4) I have so far tried the site on the lightbox fails, it takes you to the image directly, then you press the back button of the browser and it takes you back two pages, not to the gallery page.
Is there a solution to this yet please?
