Please give us a description of what happened.

Upgrade Yoast from 13.0 to 13.1 or 13.2 causes WP install to crash. Only sorted by rolling back to Yoast 13.0. Blocksy Theme is installed. Not sure how to fix.

Please describe what you expected to happen and why.

@NeilGrant24 can you please remove the plugin completely, clear the PHP Opcode cache and re-install 13.2 again? This should fix your problem. If not, you can try disabling other plugins and reverting to a default theme and try the installation again.

Hi. I don't know why I didn't think of that. I just deleted install then reinstalled straight to 13.2. It looks like it worked. Didn't need to clear PHP Opcode cache (couldn't see the tickbox in Cpanel, PHP 7.3) but it seemed to work OK without. Many thanks.
