Sorry – must’ve posted this just after LesBessant.
Drastic solution I know, but what about backing everything up , deleting, then re-installing?
Problem solved. For some reason the /wp-include/js folder was missing entirely from my install.
Have now installed it and, as you’d imagine, the editor now works a treat.
It’s always something dumb.
petit – thanks for your help.
Just tried that – still no toolbar. Checking the toolbar tag in the wordpress help it looks like a couple of other people have this problem – but no-one seems to have found a solution yet…
