Permissions set to 755 - still not working
I've manually double-checked every file and folder under the PowerGallery/Galleries directories and their permissions are all set to 755, but I'm still getting the same permissions error on that page you did and the galleries are still not working.
I've used Power CMS before on another client site with no issue - and with the same hosting company too. Really confused. Anything else you can suggest? Should I try maybe starting from scratch and seeing how that goes?
