Hi there,
Many thanks for the instruction. I've followed it, made a paid account with Wasabi, registered at Cloudlfare, created CNAME as CDN = cdn.MYSITE.com.s3.eu-central-1.wasabisys.com , changed the nameservers to Cloudflare, created a bucket at wasabi, and changed the storage at my ACP accordingly.
The files started to move, but now in the forum messages, instead of the images I see only the respective file names and 'broken' image placeholders. The URI for such files are something like: http://cdn.MYSITE.com/monthly_2019_06/IMG_20190618_002554.jpg.ea838a4773e99a2e7ff2a6e62a178a5c.jpg (Though I configured the own URL in ACP s3 service configuration as https://cdn.MYSITE.com).
What may be wrong?
Many thanks in advance!
