LiteSpeed Cache 7.8.1 compatibility issue with Tutor LMS 4.0.4 course archive

[Anji]

Hi,

I believe I have found a compatibility issue between LiteSpeed Cache 7.8.1 and Tutor LMS 4.0.4.
When a Tutor LMS course is changed from Draft to Published, the Courses archive page (/courses/) displays "No Data Available in this Section".
If I interact with the Sort dropdown (for example, changing the sort order), the course immediately appears without reloading the page. This suggests the course exists, but the initial page is serving stale or incorrectly cached content until an AJAX refresh occurs.
I have completed extensive troubleshooting:

• WordPress 7.0.2
• Tutor LMS 4.0.4
• LiteSpeed Cache 7.8.1
• Hostinger Business Web Hosting (LiteSpeed Web Server)
• JS Combine: OFF
• JS Minify: OFF
• Guest Mode: OFF
• Guest Optimisation: OFF
• QUIC.cloud: Disabled
• Browser cache and server cache purged multiple times
• Permalinks resaved
• Tested in Incognito

Most importantly, if I disable the LiteSpeed Cache plugin completely, the problem disappears immediately.
With the plugin disabled:

• Publishing a course works correctly.
• The course archive updates immediately.
• No interaction with the sort dropdown is required.

Could you please advise whether this is a known compatibility issue with Tutor LMS, or whether this should be considered a bug in LiteSpeed Cache?
Thank you.​
