Hi, I’ve updated to latest commit in master (8702ded6a1d5780903c5344b1240707e498bda7a) and now the update daemon fails to start with this error:

This is in a Fedora 28 server, with PHP 7.2.4, and using MariaDB 10.2.14 as database.

check tt-rss system error log in preferences for any additional information

other than that, this particular query hasn’t been updated in a while so idk what could go wrong

Somehow this isn’t happening any more. Maybe a system update.

Thank you.
