I have been using 1.0 version and just now updated to 2.1.9.
I made a complete clean installation with empty database.
No problems during installation.
When I try to edit news items, I will just get empty content. I can create new items, but I can't edit them.
I have tested with PHP 7.1 & 7.3 - no difference. However, it seems that occasionally it works. Some news items seems to work better, some not at all.
In PHP Info there is a message at top
allow_url_fopen: If you have Curl enabled, you should consider disabling this feature.
expose_php: Disabling this will hide your PHP version from browsers.
