After my client updated her 3.5.3 ATO to the latest WP3, she said she can no longer use HTML button on posts. I logged in and agreed. its not working.
At first it was the VISUAL tab that didnt work and HTML did, now its the opposite.
Nothing was changed except updating WP3 latest version, 3.0.2.

Can you help advise?
Thanks so much

disable all plugins and see what happens

Thanks!!
I forgot completely to try that!!
I disabled them all, went back into POSTS and the buttons worked.
So then I went back and reactivated one at a time while checking back on POSTS to see if the VISUAL/HTML tabs stayed activated.

I found that it was the My Social Links Bar that broke it.
They must just need to update to be compatible with the new WP update.

THANKS AGAIN!!
Gonna go send you a thank you payment!!
