Menu breaks with latest version of plugin

Hi, I recently updated your plugin to version 0.9.69.1, and when I made the change it broke the main navigation menu on my site. By deactivating the plugin, my menu returns to normal. It is currently set as deactivated so that my site functions properly.

I made the update to my staging site and had no issues, however when I updated the plugin on my live site it breaks the menu. The only difference between the two sites is that on the staging version, the Jetpack plugin is set to Safe Mode and search engine visibility is turned off.

My host pulled these backend logs and suggested I contact you in order to determine what might be causing this behavior. Backend log: PHP Warning: Illegal string offset ‘itemprop’ in /wp-content/plugins/accelerated-mobile-pages/templates/features.php on line 4967\n

The page I need help with: [log in to see the link]
