Thank you for reaching out! Generally speaking, our latest Cloudinary WordPress Plug-in should be compatible with WordPress version 4.7 or higher and we have tested up to 6.0.1. In order to further troubleshoot, I may have to ask for details on your environment/account if you need further assistance, if so then please proceed in opening an support ticket to us at https://support.cloudinary.com/hc/en-us/requests/new
I confirm that it was not an issue caused solely by Cloudinary. Rather, it was a conflict between Cloudinary plugin with another plugin called “External Links – nofollow, noopener & new window” By WebFactory I’ve used on the site, after many tries. By tweaking the configuration of that plugin, I made Cloudinary back to work smoothly again.
