CDN mapping not working

A few months back, I logged an issue: using CDN within the LS cache plugin leads to weird image sizes. I was asked to email the support but never got a response, even after two months. I thought this might be an issue from my CDN provider, so I switched to a different CDN, and not to my surprise, it still causes those issues.

So, I thought I could use a different plugin for just CDN. It is already frustrating that I must use a different CDN plugin. But I don’t have a choice. But now, none of the URLs are getting rewritten with the CDN URL, even if I add and use the CDN option within the LS cache plugin. I’ve tried everything I can think of, including using different plugins, clearing the cache, disabling and deleting all plugins, and removing all tables and options from the database. Nothing has worked.

This is really starting to feel like a lack of support, or worse, ignorance. I need to be able to use my own CDN, and I don’t want to be locked into using the QUIC cloud.

Please, please, please help me get this working. I’m at my wit’s end.
