ajax request 403 error

Hello,

I am experiencing an issue across all my clients’ websites when LiteSpeed Cache is active. Specifically, Ajax requests related to functions like user login or adding products to the cart return a 403 Forbidden error. I have tried most solutions suggested in forums (e.g., enabling ESI), but they did not resolve the issue. Enabling ESI even caused a new problem where logged-in users occasionally see other users’ data.

Could you please advise if there are specific LiteSpeed Cache settings I need to enable or disable to prevent 403 errors for Ajax requests involving actions like login or add-to-cart?

Thank you!
