Cannot upgrade ACF Pro from 5.9.9 to 5.10 (or 5.10.1) because this plugin complains with
“Advanced Custom Fields should be on version 5.6.0 or above”
In the world of versioning 5.10 is higher than 5.9
This should be an easy fix, but strangely has not been sorted. Odd considering ACF is a requirement.
More about this error here: https://wordpress.org/support/topic/advanced-custom-fields-should-be-on-version-5-6-0-or-above/
This is something that will need to be dealt with by the author of the other plugin.
@cmbsmr has the gist of it. It is they way that the developer is detecting the version number of ACF. But this should be done using version_compare() instead of comparing them as numbers or strings.
