I have typo3 version 7.6.20 with php 7.3.26 and would provide a file for downloading only for registrated users. What will be the best way. This ext Download Manager tells me, that my PHP version is to high. And that ext secure download causes my system to crash. (I get this error: error and reseting my typo3 system) What is compatible or what could I do? Thanks Walter
Well - since both, TYPO3 and PHP are quite outdated, IMHO the thing you should do in the first place is: Upgrade that system immediately to CMS 10 at least, maybe CMS 9 with ELTS support, and PHP 7.4.
Download Manager is available up to CMS 11, so your actual problem should be fixed by those upgrades too.
