unfortunately the error of an update from tt_products 1.2.7 to 2.4.6 is
still not solved.
TYPO3 Fatal Error: Extension key "table" was NOT loaded!
(t3lib_extMgm::extPath)

I send you some debug info I have gathered. It is the output after the
download of the extension from TER and before pressing the 'Make
updates' button. If you need more info, just tell me.


Regards,

Franz
