Uncaught Error: Class ‘AmpProject\\Exception\\FailedToGet…

Today I started getting a bunch of fatal errors in our the Apache error log. This is similar to another post from last year, but it didn’t provide a solution.

AH01071: Got error 'PHP message: PHP Fatal error:  Uncaught Error: Class 'AmpProject\\Exception\\FailedToGetFromRemoteUrl' not found in /var/www/html/blog/wp-content/plugins/accelerated-mobile-pages/includes/vendor/tool/RemoteRequest/CurlRemoteGetRequest.php:142\n

Stack trace:\n
