AH.
It works now! I re-uploaded the entire wp-includes folder (again) and this time it all works fine, sorry for bothering you.
Hi,
I am having same problem all of a sudden. Upgraded from 2.0.6 to 2.1.1 last week. The rich text editor would not work for me (it did not show up on the write entry pages) and I saw a solution somewhere else that said I had corrupt wp_includes folder. I uploaded again from scratch and now I get this error about the missing getEditorTemplate.
Anyone help me please?
