    Dear Support,

    We have a caching issue with the Litespeed cache plugin and the FB Conversion API (i.e. server side events).

    We have implemented the FB pixel via the WP-plugin PixelYourSite, both as a browser pixel and as a server side event (conversion API).

    The issue we experience is described in this video:

    You can easily replicate the issue by loading our website per the instructions in the video above:

    How do suggest that we solve this problem where it is specifically related to the Litespeed cache plugin and de-duplicating FB events?

    I look forward to your help with this issue.

    Dear @serwer20

    Many thanks for lending your support to this issue.

    We suspect most e-commerce website that use Litespeed and FB tracking (pixel & API) will experience this issue.

    Dear @qtwrk

    Many thanks for the suggestion.

    We have tried it but sadly it did not make any difference, the event ID stays the same.

    As per your instructions:
    – we disabled JS push & defer via Litspeed Cache > Page Optimisation > JS HTTP/2 Push off & Load JS Deferred off
    – we then cleared the cache via Litespeed Cache > Toolbox > Empty Entire Cache
    – we also cleared the entire Cloudflare Cache,
    – last we ensured that the browser cache was clear and checked with the FB Pixel Helper in three different browsers: Chrome, Opera, New Edge (Chromium)

    We found that the event ID was the same in all three browsers.

    Would you like me to send you a new report number so you can investigate further?

    Many thanks for your help with this problem.

    Kind regards,

    Dear @qtwrk

    Another quick update:

    We switched-off the Litespeed Cache plugin and the problem was solved.

    We then tried the WP-Rocket Caching plugin and with this caching plugin we did not experience the issue.

    Hence, the issue is quite clearly associated with the Litespeed Cache plugin.

    Dear @qtwrk

    I was wondering whether excluding Facebook tracking from being cached might be a solution.

    This is what we have in mind:

    These are the mentions of Facebook that we find on the ‘waterfall’ when we run our site through speed testing tools, e.g. Pingdome, WebPageTest.org.

    Could this work?

    Dear @qtwrk

    The author of the plugin PixelYourSite found a way to solve this issue for caching plugins like Litespeed by using Ajax.

    We found that this solution works for our website.

    Here is a screenshot to show this setting:
