htmlArea RTE not loading in TYPO3 6.2

Question

I have just migrated six websites from TYPO3 4.x to TYPO3 6.2 In all of these, I use the htmlArea RTE, but only in one of these, the RTE does not work.

It's installed fine, but when I open a content element, the RTE keeps trying to load and simply does not open.

I know that there was a bug related to this (TYPO3 can't enable htmlArea RTE) but this is NOT the solution for my problem.

Because all my other TYPO3 installations work fine, I am really clueless and would appreciate any help.

Answer 1

SOLVED! Just in case anyone else is having a similar problem:

In my PageTSConfig, I had this entry: RTE.default.buttons.blockstyle.tags.table.allowedClasses.classesTD

But it needs to be this: RTE.default.buttons.blockstyle.tags.table.allowedClasses

Now everything works perfectly
