Attempt to run TinyTinyRss on shared hosting, despite their warnings in their documentation that it won't work: Failed.
I mean: I *do* have ssh access, but somehow HostEurope configures PHP/MySQL strangely.
Running the updater on the command line first resulted in
PDO [2002] No such file or directory
and after setting host to 127.0.0.1 to
[2002] Connection timed out
