[TYPO3-dev] 4.5.19: loadTCA infinity loop/recursion

[Ernesto Baschny [cron IT]]

Hi,

could you further check if this also happens in latest 4.5.x (currently
4.5.27)?

Also please try to unload unneeded extensions to see if any of it is
interfering with this (maybe through a Hook or a XCLASS) so that we can
be sure if this is a Core issue or an Extension issue.

Regards,
Ernesto
