Hi,
I'm in the middle of testing (locally) the upgrade path from WP2.7.1 to 3.1 and ATA 3.3.3 to 3.6.4 before upgrading my hosted site. I have most of it mapped out, including the plugins, except one: TinyMCE Advanced.
On the WP site there seems to be a number of reports of TinyMCE Advanced 3.3.9 being broken under 3.1. In googling this plugin to find out more, I found the TinyMCE site which has V3.4.1. Except it doesn't seem to be "plugin ready". At least not at my JSQuery, WP, ATA skill level.
Has anyone configured this version for 3.1 and/or ATA? If so, does it work? Or is there an equal or better alternative to TinyMCE Advanced? I really, really, really depend on those extra features to write and configure my posts.
P.S. Messed up the Subject Line should be "TinyMCE Upgrade/Replacement?
