Wordpress LScache Plugin: Page broken on Apple devices
Last Updated on: Wed, 15 Apr 2026 00:00:02 OK, this is an odd one so Ill give all the info I can. My staging site works fine on all devices but when I push it live, it fails on iPhone/iPad (all browsers) and when using Safari on macOS. The live site works in Chrome on macOS. If I disable LiteSpeed, the site works across all devices. If I leave LiteSpeed enabled but revert the .htaccess to the WordPress default, the site works. Its worth noting that the .htaccess that fails on the live site is identical to the .htaccess that works on the staging site. Sometimes the home page will load almost correctly (missing the image). Sometimes a single page will seem to load correctly. In both cases, other pages remain broken. They display as though the CSS is missing. I looked at similar posts and found that users were reporting this problem if JS HTTP/2 Push is active, which it was. So I set that to inactive, but the issue remains. CSS HTTP/2 Push was already inactive. Another related post spoke of 404 getting errors. I am getting 404 errors on /wp-content/litespeed/cssjs/f5bb9.js and /wp-content/litespeed/cssjs/f58a9.js when it fails. There are no 404s when the page loads correctly. The live and staging sites are on the same server and had the same LiteSpeed settings. As I said, the staging and live .htaccess files were identical. The devices that I am seeing a problem on are: Safari 13.1.1 on macOS 10.13.6 and 10.15.5 Safari, Chrome and Brave on iOS 13.5.1 I dont see the problem on: Non-Apple devices Chrome or Brave Browser on macOS 10.13.6 and 10.15.5 The child theme contains a few short-codes and a small amount of CSS.

Best regards, It still happens. Hi, Could you please try if you reset to default setting , purge all , and how it goes ? I would think might be CSS related options Best regards, Hi, @mkwm please create a separated topic your issue. Best regards, Hi, @anotheruserhere Do you still need help with this? If so, we need to figure out which setting is causing the problem. To diagnose this, start by exporting your current configuration as a backup, and then resetting LiteSpeed Cache to the default settings, like so: Go to LiteSpeed Cache > Toolbox > Import/Export to find those tools. Once youve done that, switch to the Purge tab and Purge All. Then see if the problem persists, and let us know what happens. Well give you next steps from there. Im going to mark this topic Resolved for now, but if you still want to troubleshoot, please take the steps I just mentioned and we will be happy to reopen the topic. Thanks!
