Cache not working

Can you provide the site URL you are trying to use CE on? Also, have you tried disabling all plugins and switching to a default theme to see if the issue persists?

This site is under HTTP authorization. Can I send you username and password safely?

I found that if I deactivated Autoptimize plugin, cache works good.
It is also same on my local machine. When Autoptimize plugin is active, Cache enabler does not save static pages.

Thank you

Have you tried keeping Autoptimize enabled but disabling the features within the plugin’s settings? Does doing that still cause the same issue?

No. When I disable CSS and JS optimization in Autoptimize, Cache enabler works fine. When I enable one of CSS or JS optimization, cache not working.

Can you provide a screenshot of your Cache Enabler and Autoptimize settings?

Autoptimize: https://drive.google.com/file/d/14Zo3RwK00s-TZf3vNS9Ho4Y6ajp9zc8S/view?usp=drivesdk
Cache Enabler: https://drive.google.com/file/d/1loRwiZywzvDxJeDVE8Mpxnl8uDaZ0-dI/view?usp=drivesdk

Your settings look fine. And you’ve already tried disabling all other plugins besides those two?

Also, when both plugins are enabled can you check your filesystem to see if the static page generation is working?

Yes, I tried disable all plugins, it was same.

Static page generation is not working on filesystem if both plugin are active (and Autoptimize CSS or JS is enabled).

I can upload website to temporary domain and get you access to WP and FTP if you can help me.

Thank you

Hmm, are you receiving any console errors?

Perhaps there is a conflict with your configuration somewhere or maybe your theme. I would spin up a new test site with only CE and Autoptimize enabled with a default theme to try to further rule out whether it’s related to your server config or WordPress setup.

Oh, when I was debugging Autoptimize I place this code to functions.php:
add_filter('autoptimize_filter_obkiller','__return_true');

Then I forgot to delete this line.

Now everything is ok.

Thank you

that indeed is a dangerous filter @matoni555;

// filter to be used with care, kills all output buffers when true. use with extreme caution. you have been warned!

glad you remembered & fixed! ??
