I have a website running WordPress 3.3.1 since 2012 (or so), which was displaying the Admin pages perfectly back then.
I have not performed much administration since then, as the site itself (wp-content) continues to function and display perfectly till these days.
But I recently discovered that all of its Admin pages (wp-admin) now show up blank.
I suspect this is due to an update in PHP version performed by my web host (5.4.x to 8.2.18) and I would like to upgrade my WordPress version to match this installed PHP 8.2.18 version. It is a good idea anyway to stay current with the latest WordPress version.
I started following the instructions on how to perform such an upgrade manually at https://developer.projectdmc.org/advanced-administration/upgrade/upgrading/#upgrading-wordpress-extended-instructions
Steps 1-3 (backup etc.) went without incident but when reached step 4 (“Deactivate ALL your Plugins“), I hit a catch22 wall: In order to do that I need that admin page to be visible. But it isn’t.
How do I deactivate all my WordPress 3.3.1 plugins despite the wp-admin page being blank?
Thank you
