Lately I’ve been upgrading some websites built on umbraco 4.0.x.
Most of these websites were using object tags in the TinyMCE editor to show rich content, like flash, but since we upgraded those websites to 4.7.1, the object tag wasn’t displayed anymore in the HTML of the TinyMCE editor.
So when changing and publishing such page, the object tags get removed from the front-end, because they were missing in TinyMCE itself.
This is really annoying ofcourse, because some pages couldn’t be edited anymore. I’ve looked around the net for solutions/other people experiencing the same problem.
There are some bug reports on Codeplex, but these are other problems than I was facing.
So I just thought; let’s upgrade TinyMCE included in umbraco from version 3.4 to 3.4.7 and this fixed my problem.
There are some bug reports on Codeplex to upgrade TinyMCE (and jQuery) to the latest version. Please vote for them!
