Missing Product Images After Upgrading From 2.2.10 to 2.3.4



I’ve just upgraded my site from 2.2.10 to 2.3.4, but now when I check the catalog and product pages on the front end, all my product images are missing, and just displaying the standard Magento image place holder.


I’ve tried running ‘bin/magento indexer:reindex’, ‘bin/magento catalog:images:resize’ and flushing the cache, all to no avail.


When I look at the front-end page source, the images all have URLs like;




But when I check the contents of the ‘/public_html/upgradetest/pub/media/catalog/product/cache’ folder on the server, the ’60fbb9146f866f4343b37b30e54d81bd’ sub folder is entirely missing.


Has anyone got any idea how to resolve this?


Many thanks
