I had installed WP Smush Pro recently. I am unable to turn on Super-smush my images and save the settings.
Beside, the button BULK SMUSH NOW and ATTACHMENTS SUPER-SMUSHED ENABLE Button is not working too.
My site is http://www.georgetownheritage.com/.
I had grant access to your dev team. Please fix this ASAP as the site speed is very slow.
