Not difficult.
Leave everything as it is in WordPress admin…
Go to your hosting file manager and find directory /wp-content/plugins/ and look for the wordpress-seo plugin folder
Delete the plugin folder from the file manager..
Download an older version of WordPress SEO from here https://www.ads-software.com/plugins/wordpress-seo/developers/ to your PC (I suggest version 1.5.5.3 – it’s the version I’ve reverted to using after every recent update, and seems to have the least issues)
Go back to WordPress admin and go to plugins – Add New
upload the plugin – You’ll see options at the top of the installer page e.g.
Search | Upload | Featured | etc
After it uploads, you need to reactivate the plugin
I’ve done this so often with this plugin on a number of sites and haven’t yet lost any settings (hopefully there’s not going to be a first time)
