Hello,
Thank you for contacting Rank Math support, and sorry for the unexpected delays and any inconvenience that might have been caused due to that.
1. I checked your website on a robots.txt checker and I can confirm that your site isn’t configured to block bots as you can see in my screenshot below:

2. When attempting to navigate to the categories, I can’t seem to find any 404 URLs under the /es/ language. Can you please share a specific URL for us to check?
3. I was able to replicate the issue here but the error doesn’t mention anything about our plugin so there may be some other plugins on your website that are currently causing a conflict in your search feature. To determine that, please refer to this troubleshooting guide: https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
4. As for your sitemap, I checked it on my end and the sitemap page seems to be loading just fine. I also went ahead and submitted it on a sitemap validator and it is returning with no errors as you can see here:

I went ahead and followed this video guide to flush your sitemap cache.
Please proceed with excluding the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:
https://rankmath.com/kb/exclude-sitemaps-from-caching/
After doing so, remove all your sitemaps from your GSC and resubmit only the primary sitemap (sitemap_index.xml).
Let us know how that goes. Looking forward to helping you on this one.
It’s like I’m talking to a wall. Once again, read carefully – and get the point, I did not say that in robots banned googlebot, I said that the main pages of the site https://i-aria.fun and https://i-aria.fun/es/ in Russian and Spanish are banned, is the tag noindex. I have not banned indexing these pages, so how come? And how do I change this? That was my question. And you show me what I already know.
I didn’t say the site map was in error. Once again I repeat for the hundredth time and hope that you will hear me – the sitemap is not recognized only by Google, with other search engines no such problems. Maybe the problem is in google, what do you think? And if you say that all is well and your plugin has nothing to do with it. There is only one way left to check everything. Delete and clean up the tables in the database. Install another SEO plugin and see what happens.
Sometimes it takes time. I am sure that if you will give it some time, it will surely be indexed
Hello,
I apologize if my previous response didn’t help you with your concern.
Checking both your homepage in the view source, the robots tag is already set to index as you can see in my screenshot below:

I did a site:https://i-aria.fun/es/ and site:https://i-aria.fun and they are both indexed on the SERP.
Could you please share some insights on how you determined that your homepages are blocked in the countries you mentioned?
As for your sitemap, sometimes search engines aren’t able to read the latest version or even the working version right away. It could be cached or the search engine hasn’t re-crawled it yet so you may give it some time.
You may follow the steps I presented to exclude the sitemap cache then follow this video screen guide: https://i.rankmath.com/pipRDp
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
