Hi,
After several hours of beating my head against the wall experiencing the exact same issue as vsPiotr while attempting to embed the "new" Vimeo video into a page, I am faced with having to revive this thread. I am using ZenPhoto version 1.3, and have made multiple attempts at following the troubleshooting thread given above - except for the correct one. I have enabled the "class-textobject" plugin and uploaded the Vimeo embed as a .txt file into media (also ftp into a folder), but have been unsuccessful at getting it into the page with either the image or embedded media uploader from tinyMCE. I have even tried entering the embed code directly into the HTML window, but is disappears upon update. What am I missing besides (and including) the obvious? Anybody?
Thanks in advance.
