I know that MonsterInsights provides a mechanism for doing this, and that plugin also provides integration for InstantArticles in GA. Maybe that’s worth a look? Trying to get support from these guys is like trying to get blood out of a stone.
It means the plugin developer needs to get their finger out and update it. There is a version check in the code which is failing. Instead of speeding the site up it’s effectively slowing it down.
I’m also seeing something similar – Fatal error: Call to undefined function apply_filter() in /var/sites/r/rochdaleherald.co.uk/public_html/wp-content/plugins/postie/postie-functions.php on line 1754
I am using Magazine Basic on our site and the logo doesn’t display on the mobile site. Instead it displays the site title. What can I do to fix this?
