Hi Frank,

Thanks for the answers.

Hi,

Thanks for the reply.

Just to clarify, here’s my setup. I’m using KeyCDN with Cache Enabler, CDN Enabler, Optimus, Nginx Cache, Redis Cache and Autoptimize.

The slider that seems to have trouble loading when Autoptimize is enabled, is Slider Revolution 5.

In Autoptimize, I have the following settings toggled:

Optimize html, js, css
Also aggregate inline js
Generate data: URIs for images
Also aggregate inline css
Exclude css from Autoptimize: admin-bar.min.css, dashicons.min.css
CDN base URL: included
Save aggregated script/css as static files? Yes
Also optimize for logged in users? Yes

Cached info: Cached styles and scripts 76 files, totalling 5405 Kbytes (calculated at 21:01 UTC)

Can you see any possible issues?

Also:

Should Autoptimize have created two files to load the page? Or is one a legacy from some purge? Your above answer seems to imply that the Autoptimize file getting the error response shouldn’t be there and that it is only getting called because of a improperly purged cache, that has an html reference to the missing file? Am I getting that right?

Finally:

As a stop gap to the issue, I disabled Autoptimize. Now I am unable to enable again. It gives the plugin enabled notice but either doesn’t enable at all or enables briefly and then disables (usually when I try to save settings).

Thanks for taking the time to read this and for your help.

Actually, I’m now experiencing erratic and randomly huge hang times loading the front page and other pages.

Sometimes the page load is very fast. Others will just pulse the load animation indefinitely. This is particularly bad on the two pages with revolution sliders. And it is not behavior I experienced before using Autoptimize.

Sometimes it will take several seconds before the browser even responds to the inputted address. Then once it starts loading the page, sometimes it will load reasonably quickly, while it go on for upwards of 6-10 seconds. Other times the loading animation will just keep going indefinitely, never loading the page.

The inconsistency is baffling.

Perfect. Thanks Mikko.

Thanks.

I think that might be the relevant issue, as I’m using Visual Composer on my site.

Would you suggest using the code that Itamar Megged mentioned in the comments (https://www.relevanssi.com/knowledge-base/divi-page-builder-and-cleaner-excerpts/) or your original “Get rid of all shortcodes” version?

Thanks again.
