Thanks for the additional information!
Role Scoper has caused trouble in the past:
[mla_gallery] working only for the author
I posted to the Role Scoper support forum 2 months ago, but have not received any response. It's possible that updates to Role Scoper since then have created new interaction issues. I have not tested Easy Content Types. I will do some testing with both of these plugins and see what I can find.
By the way, I don't see "Easy Content Types" in the WordPress directory - is that the exact name? Can you tell me the author or give me a link?
If it's possible, try temporarily deactivating one or both of those plugins and see if the problem goes away. If it does, re-activate them one at a time and see when the problem returns. That would be a clue...
If you're feeling adventurous, try adding
mla_debug=true to one or more of your
[mla_gallery] shortcodes. You should see a lot of debugging information added to the post/page containing the gallery. Don't do this on a public/production site - it's pretty ugly!
If you get some debugging results I'd love to see them. If you're willing to do that or you have other information you don't want to post here, go to the Our Story/Contact Us (http://fairtradejudaica.org/our-story/contact-us/) page at fairtradejudaica.org and give me your e-mail address. I'll send you my e-mail address and we can exchange more information.
Thanks again for using the Media Library Assistant and for your patience while I work on this issue.
