I had to disable BD cache, because I still get AMP related errors even when The AMP feature is disabled. Server error log : ErrorException: Fatal Error: Class 'bdImage_ShippableHelper_ImageSize' not found - library/bdCache/ShippableHelper/ImageSize.php:17 Google sent me also this message:
Looks like you installed [bd] Image but some older version. Please consider updating to v1.2.2 (https://xfrocks.com/resources/bd-image.32/download?version=178) Regarding the AMP errors, once Google found your AMP page they won't remove it even after you disable the amp link from real pages. This may be a bug on their bots I think. Or maybe it will take sometime for them to drop those pages.
