TYPO3 Core

When strings were extracted from the admin panel code to language files, their meaning was changed to the opposite but the code was not changed. Original (4.x) code was:

$tableArr[] = array('no_cache:', $GLOBALS['TSFE']->no_cache ? 1 : 0);

So it displayed the "no_cache: 1" when the page is not cached.

Current code:

$tableArr[] = array($this->extGetLL('info_noCache'), $GLOBALS['TSFE']->no_cache ? 1 : 0);

and

<trans-unit id="info_noCache" xml:space="preserve">
<source>Page cached</source>
</trans-unit>

This means that "Page cached: 0" will be displayed in the admin panel when the page is actually cached. This can be verified easily: just click "Disable caching in the admin panel and see "Page cached: 1" in the "Info" section.
