Hi,
> Do I need to downgrade to 7.3 or which version will work? I
Only you, from the WordPress plugins you have installed, can know which versions of PHP they are compatible with.
You say it works with PHP 7.0.10, so try PHP 7.1.33, then 7.2.34, then 7.3.25.
It only takes a few minutes to download the PHP addons and install them.
You can also check with the plugin vendors to find out which versions of PHP they are compatible with.
As for PhpMyAdmin, version 4.9.7 supports PHP 5.5, 5.6 and 7.0.
All addons are on
