Breaking: #82803 - Global configuration option “content_doktypes” removed¶
See Issue #82803
The configuration option
$TYPO3_CONF_VARS['FE']['content_doktypes'] which declared
what pages.doktypes values could contain content elements, was removed.
Using this option in custom code will lead to unexpected behaviour.
Changing this option has no effect on TYPO3 Core anymore.
Installations having this option explicitly set.
Remove all usages working with this option.
