TYPO3 Core

This probably was reported before, but was then fixed and has now reappeared: https://forge.typo3.org/issues/85087

I usually don't use Fluid debug output in adminpanel and usually don't enable it on production but I did that recently by accident.

Several days later I loaded a page, the debug output was displayed, the admin panel was not even activated.

What made matters worse, the debug output was also displayed if not logged in the BE (using different browser).

versions¶

• reproduced in v11, did not check newer versions yet.

Reproduce¶

1. Flush all cache (including system cache)
2. Enable admin panel
3. Activate checkbox "Fluid debug output"
4. Load page: debug output is displayed) (ok)
5. deactivate adminpanel (via the toggle)
6. load page again: debug output is displayed (unexpected)
7. load page in different browser (not logged in): debug output is displayed (bad)
8. Deactivate the checkbox "Fluid debug output"
9. refresh page CTRL-SHIFT-r (or flush cache in adminpanel): debug output still displayed

finally, flush cache

vendor/bin/typo3 cache:flush

Is now ok

Suggestion¶

I think this should be changed (at least in production context)

• the debug output should not be saved
• or better: not possible to enable "Fluid debug" checkbox in production context
