TYPO3 Core

Didi you delete the cache/temporary files of your browser? 99,9% browser-cache is the issue with RTE not loading. Please also note there had been some issues with IE8. Are you using IE8?

The picture looks as if the RTE skin was not loaded.

Please try to clear the browser cache.

When moving the <link> tags to the HTML head a title attribute ("HTMLArea RTE Skin") was added. This causes problems because the "title" attribute triggers alternative stylesheets in the browser. See HTML 4.0.1 standard [1].

If the title attribute(s) introduced in revision 4297 [2] were not set intentionally I'd suggest to remove them. From the description of bug #9516 it doesn't seem to be intentionally.

I nearly forgot the workaround: select the correct stylesheet from your browser menu

Please test the patch attached to issue #10665.

The patch for bug #10665 addresses and solves this issue.

Sorry I had not time to work on it.
But finaly I found the issue and want to add the solution.

Is a wrong setting in the php.ini
the basedir was still on a other typo3 directory.
Like
d:\inetpub\Typo3_4.2.1 while this is the d:\inetpub\typo3_4.2.6
So my own stupid mistake.
I found it because text/w pic was not showing any pictures.
that pointed me in the right direction.
Sorry
