Hello,
just checked my page with GTMetrix and noticed that for my translated product pages (English), there are two ?wc-ajax=get_refreshed_fragments calls. They are exactly the same, so I don't know why they load twice. In default language (German) it loads only once.
As this is very bad for performance, I would be happy if you could help me. Thank you.
I took a look at the website and I could not replicate the issue. The behavior I see is that wc-ajax is only called once when you switch languages or on the first visit to the homepage or shop page. Please provide steps to recreate the call happening twice.
I believe this is something that you may have better luck looking at with WooCommerce support since we have not seen it with other clients using WooCommerce and WPML.
However, I will be happy to take a deeper look if you can provide steps to recreate the problem or provide screenshots showing when it happens, along with the details of the actual calls. If the calls are literally exactly the same, then we would need temporary access to your website to debug further.
Thank you for your clarification. I was able to replicate the issue without GT Metrix. It happens when you directly visit a product URL in a new tab or window. This is the only time it happens for the translated language. The reason you see it in GT Metrix every time is that it is like opening a new browser window and typing in the URL.
If I refresh the product or continue browsing on your website then it is only called once, or sometimes never called (which is normal).
I have enabled private responses on your next reply so that I can take a look and confirm exactly what triggers this. However, in order to see a real performance difference on your website, you may want to look into disabling this completely, or using a plugin like WP Rocket to optimize this WooCommerce feature: hidden link hidden link
It appears my last response never sent due to a technical problem.
According to my team, the double call usually happens when we must fetch translated cart fragments, and using WP Rocket optimization should mean that the second call is retrieved from the cache if the call and response are exactly the same, thus causing no real performance hit.
I have tried to see what the actual performance decrease is on your live site and I could only find a single call, as seen in the screenshot.
Perhaps you made some changes or applied some updates to your live site?
Hi Izzy,
thank you. Yes, it seems that the double call has gone. I made a few updates (WPML, Woocommerce), so I guess that its fixed. But now there is this red "undefined" request. This request appears only on my translated pages, so it may be WPML related. I have to figure out what this is....could you please help me?
And could you delete the screenshot please? Thank you.
I've deleted the screenshot. I did see the "undefined" error too but I can't find it anymore. I'm not sure that it is WPML related but I'll be happy to take another look if you think it is.
Please either mark this ticket as resolved, or let me know if you think the new issue is WPML related and I'll split it into a new ticket.
