okay. I seem to have gotten 2.5 working... somewhat... All of the ame tags that were dead in my forums from running into all of the problems before are now displaying videos, yeah!!
But, no new embeds work. URL's don't get converted to the ame tag
I have:
Disable New Items -> No
Extract Destination Data -> Yes
Enable File Cache -> Yes (and CHMOD 777 the amecache folder)
Posting, vbBlogs, Social Group & Visitor Message Settings -> Yes
Was there something else that I'm missing?
EDIT: There must have been something wrong with the original file import. I just re-imported the product-ame.xml file and it's working fine now.
