Do you see any JavaScript errors on the browser console before or after trying to save stevantic ?
I have the same problem, after pressing save:
/wp-admin/admin-ajax.php:1 server responded with a 400 ()
A 400 error response? I’m suspecting a plugin conflict of some sort, can you try disabling other plugins to see if you can identify a culprit?
I fixed it by disabling another plugin, now my images won’t cache since the other plugin is deactivated. Does your main plugin also cache images on client side?
no, it does nothing with images I’m afraid. can I ask what plugin was causing AsyncJS settings not to save?
W3 total cache. Do you have a good image cacher? I only need image caching nothing else. Also AutoOptimize adds unused CSS, how can I disable this?
What does W3TC do with images, does it integrate with a image optimizing CDN and if so which one?
re. unused CSS; AO merely combines & minifies your theme & plugins CSS, but it does not know what CSS is used/ unused and as such cannot remove unused CSS. if you want to tackle this, you might want to look into “rapidload”, a premium service which removes unused CSS, see the info on the “optimize more” tab in Autoptimize.
To be honest I don’t know how to answer those questions I removed W3TC ^^… So there is no way to cache jpg’s?
but jpg’s are static files, so there’s no need/ use to cache them (on the server at least).
if you’re talking about permitting caching of images in the browser though, that typically is done by webserver-configuration, see https://www.keycdn.com/support/cache-control for more info. assuming you’re on Apache, you could try https://wordpress.org/plugins/add-expires-headers/ or https://wordpress.org/plugins/far-future-expiry-header/ out (never used them myself though).
I mean client-side, I will look into the expire-headers. Also, I have 13 plugins, one of them has a critical A PHP session was created by a session_start() function call. This isn’t your plugins right? Than I can rule 2 out.
Indeed AO nor AsyncJS use PHP-sessions.
Good I found the problem within the Unyson framework, Thanks for your help, love your product!
