Try setting the CDN URL in Autoptimize as well, this will allow it to understand files on that URL are to be considered local too, ensuring those will be picked up as well.
I have the same problem with my site. I have specified the CDN url and the issue persists – both js and css are not combined. I’ve noticed that this only happens when logged out of WordPress. When logged in, the combining/minification works. I tried downgrading to 2.5.1 but that did not change anything.
I have another site using AO on the same webhost/CDN, same wordpress theme – AO works just fine there. Really not sure what the difference is between the two sites and why it works for one and not the other.
can you share that site’s URL tegid ?
some ideas/ questions/ pointers;
* try setting the CDN URL in AO including https:
(would be surprised this would help, but well ..)
* it looks like this may be an output buffer related issue as even though autoptimize lazysizes JS is included, the images themself don’t have the lazyload class added.
* are there any errors in your php errorlog?
* could be a plugin conflict, maybe try identifying plugins used on tradingpostbrewing not used on relishcateringco and try to disable those for a second?
Thank you so much! I believe this was caused by the Convert Plus plugin (they called out something about buffer in the 3.5.3 changelog).
Thank you for being so generous with your time – I should have done a complete plugin check before posting but I got ahead of myself!
