Using Selfoss with PHP 8
FWIW, I'm using Selfoss 2.19-8941a31 on PHP 8.0.13 and am not seeing any problems with the "star" or "mark as read" features.
I am seeing other problems, most significantly, that some RSS feeds are not getting updated (with a "connection timed out" message) even though they were fine under Selfoss 2.18 and I can visit them in my browser with no problem. I wasn't sure whether it made sense to submit a bug report for a nightly build, but I can make a fuller post about this here or on GitHub if anyone wants.
