I’ve been trying all day to upgrade our WordPress server running PHP 7 with php-fpm on Virtualmin on Ubuntu 16.04 to a newer version of PHP. I’m frustrated as all I seem to be able to do reliably is take our production server down. I end up with WordPress being down, or errors (which seem to have more to do with php-fpm not running, or something not pointing to the right place).
Looks like there were a whole bunch of issues – a while back with 7.0 > 7.2 and Virtualmin and maybe other things too. Does any one have a foolproof way of doing this? I’ve spent an entire day on it, and I give up.
The only option I can think of is ridiculous – to build a new server on 18.04, and migrate. But, there’s so much that could go wrong there, I really don’t want to do that while I’m under such a time crunch.
Any help appreciate.
