Setup W3TC with WPML (languages on subdomains) and Yoast SEO sitemaps

Hello @biiissen

Thank you for reaching out and I am happy to help!
If the same content is served from those domains, you can add them to Page Cache > Aliases > Additional home URLs. So to confirm, yes the pages will be flushed once these are added.
As for the Preload, you can only specify a single sitemap for preloading the cache.

you cannot add more than one sitemap.

What you can do is create a nested sitemap or manually create the sitemap for all domains and add it to the Sitemap URL: field.

I hope this helps!

Thanks!

Hi @vmarko,

well technically it’s the “same” content in another language. So people could switch from the page in German to the page in English for example and then the subdomain would change (and also the slugs of course). So do you recommend adding these language subdomains to the list?

For the sitemap: So I could be having a file sitemap-int.xml for example with this content:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="https://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://de.domain.com/sitemap_index.xml</loc>
<lastmod></lastmod>
</url>
<url>
<loc>https://en.domain.com/sitemap_index.xml</loc>
<lastmod></lastmod>
</url>
<url>
<loc>https://fr.domain.com/sitemap_index.xml</loc>
<lastmod></lastmod>
</url>
</urlset>

Would that do the job also without “lastmod” being set? A quick test suggests it does. However it starts again and again from the beginning as it can’t find the already cached files. This is linked to the error messages nginx gives. But let’s discuss that in “Setup W3TC on Nginx (no proxy) & Plesk”).

And of course thanks again for your help an patience! ??

Kind regards,
Laurent

Hello @biiissen

Thank you for your feedback.

Yes, this is what I meant, if the content is the same and only language is different this should be added to the Additional home URLs
If it starts again and again from the beginning, that could be an indicator that something is flushing the cache. You may have some plugin or theme that is calling the w3tc_flush_all();

Please check the purge log (if you re-enable the W3TC) and check what may be triggering the purge.

Thanks!

Hi @vmarko,

thanks for your further information!

I had the preloading configured to restart every 200 secs and load 50 pages. And every 200 secs it started with the “sitemap-int.xml” (the one I had in my last post), it fetched the 3 URLs in there, started then fetching the XMLs generated by Yoast for the German site. After that it fetched the remaining URLs (50-x) from the Yoast sitemaps and stopped. So that was what I was expecting. After 200 secs it restarted the whole process from the beginning instead of continuing.

My best guess is that this is linked to these error messages. It checked if the page existed on the server, but couldn’t find it due to the wrong patch. So it fetched it over and over again. Or is this thought rubbish?

I’ll certainly enable your plugin again, but for now I need a break. I need the back end to be running without to much loading time for a few days, then I’ll troubleshoot the issues we discussed.

You can leave this open or mark it resolved, I’ll open a new topic then, if needed.

Thanks again and merry Christmas again!! ??

Hello @biiissen

Thank you for your feedback.
Please check the path shown in these error messages and see if the file exist there and make sure that the sitemap URL matches the server path.

Thanks!
