This question may be related to a resolved thread.
I was also missing the HTML formatting buttons, but after turning on through the custom field options, I see the formatting bar appear in the Publish for, but it is just a solid color bar with no buttons. I think this is related to my CSS problems. Another symptom is that drop-down menus have transparent backgrounds. Another post I read about that said to try uploading all the EE files again. Could the formatting button problem be resolved by that also? If I upload all the files again, do I just follow the upgrade instructions again? Thanks.
