hi, just upgraded to v2.9 and unfortunately i have the same problem described above.
before (v2.8) i could not create new tags during post creation; at least then i could fast-edit the post and add tags.
now (v2.9) i see multiple js errors in my admin page, and i can’t:
– enter tags
– fast-edit posts
– change permalink name
I looked and found my js dirs.. it seems they’re ok..
If anyone found or find the solution, please share.
Thank you
bye
S.
