For a company Typo3-Extension I have a plugin that has database entries with several text-fields for each entry. Those textfields are separeted by several tabs in the backend view (--div-- in TCA). Each of the textfield enables an RTE and the richtext editor is actually needed. In total these are >15 textfields with RTE for one entry.

Since upgrade to the 4.4.x series as well with 4.5.x (tested both with 4.4.6 and 4.5.0) the backend gets anusable when opening one of these database entries in backend to edit. It takes up to 5 min that all script elements are loaded and Firefox yells "Probable infinity loop script errors".

I set the severity to major, please correct me if you see this different. But I think this is a major bottleneck that should not be there.

Forgot the important part: with RTE disabled the "old" speed for the backend is back. This meens the page is loaded fast and the backend is fully usable again.

Hi Andreas,

i can reproduce this with an FCE element with a section which contains an RTE. I have a customer with such a FCE and approx. 30 entries. Firefox loads for about three minutes. No problem in webkit based browsers.

Do you have any bugfix for this yet?


Updated by Andreas Cord-Landwehr about 11 years ago

Hi, my temporary workaround is to part the RTEs into several tabs (DIV elements in TCA plus tabbed view) and also convince my customer to use Chromium instead of Firefox. But it is obviously only a lousy workaround.

just replace it with tinymce_rte - since TinyMCE is way faster than HTMLArea.

In wonder why the antique HTMLArea is not switched to TinyMCE in the core by default.

Thx for the hint. TinyMCE actually brings enough boost to let the extension become usable again.

Hey guys,

i can reproducse the issue too. We use TV with a section-FCE and the firefox loads many minutes or break and Chrome/Webkit have no problems?
Any suggestions? Is TinyMCE the only solution?

Can you retry on master?
Stan removed a lot of ExtJS overhead.
