Great job on the update, and thanks for the opportunity to help test…so far so good, on the front end.
The SP Admin is displaying a serif font other than the Open Sans identified in the styles. I’m guessing this may be a caching issue, though I have cleared all caches, and reset all asset optimization in our caching plugin and flushed opcache at the server level. I’ll keep at it and report back if issue persists.
More notably, the “Premium Installer” plugin I was instructed to use is not functioning as expected. In fact, after installing it, the plugin does not appear on the Plugins tab of the WP dashboard, nor on the Network Plugins tab. Thinking it might be an SP plugin, I checked the SP Plugins admin, and it does not appear there either.
I have confirmed that the premium-installer plugin was extracted and is in tact. But I have no way of activating it. Issue occurs in Firefox and Chrome.
WordPress Multisite Network Installation
WP v.5.3
I’ll use this thread to report any other issues I come across…
