Smushing interface at media library shows forever smushing. The smushing icon goes round and round forever. But if I refresh the page it will shows that the smushing process finished already.
So everytime I smush any image in media library, I have to wait and refresh the page everytime.
It happens only with this website of mine (reedthai.com). Another website of mine that uses SmushPro has no problem at all. Both websites are on the same server, same php version, same mariaDB version.
please see screenshot for more information
