I'm getting the following error. Having posted it in the GitHub I realise I should post it here instead.
Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/vhosts/domain.com/httpdocs/site/assets/cache/FileCompiler/site/modules/MarkupSEO/MarkupSEO.module on line 245
I know MarkupSEO is an old and relatively discontinued Module these days but was hoping to fix by upgrading both PHP and PW to latter versions.
I am now running ProcessWire 3.0.148 © 2020 and PHP 7.3.13
Issue persists.
