Hi ,
I got the same issue with new aws plugins in our multisite environment.
I have updated both “amazon-s3-and-cloudfront” and “amazon-web-services”
and found the same issue which you guys found but in only one post type related with email in our system.
what i did to fix that is commented one function call in below file :
wp-content/plugins/amazon-s3-and-cloudfront/classes/as3cf-filter.php
function name : find_urls_and_replace
and commented code in this function. : //$value = $this->replace_urls( $value, $url_pairs );
I still have one issue left with this new plugin when I share post between two stations , image in child station comes busted I am still working on that but you guys can try above thing and do fresh test and see if that works
for you guys.
Thanks,
Dipak.
