Sitemap Issues

Hi.

I’ve been using RankMath for several years now, but over the past few months, I’ve experienced lots of issues with the Sitemap for one of my websites (spookysight.com). Google Search Console can only read some of the items in the sitemap (https://spookysight.com/sitemap_index.xml):

– 73 out of the 95 posts have been discovered (despite the fact I manually requested each of the 95 to be indexed, and 91 of them are currently indexed).
– 0 out of 14 categories have been discovered, and I’m getting the “Couldn’t fetch” and ”
Sitemap could not be read” error message in Google Search Console.
– 0 out of the 6 pages have been discovered. Same errors as above.

On top of that, every few days some of my posts are being temporarily removed from Google Search Results due to “Temporary Sitemap Error” and I have to manually resubmit them.

And another issue: some posts (like this one https://spookysight.com/ghost-hunting-equipment-full-checklist/) show as “URL not in Google” because “No referring sitemaps detected” and Crawl and Indexing sections are all N/A. That despite manually submitting these pages 10+ times so far.

I don’t know what’s going on. I had issues with Bing too. Bing could only read 40-50% of the entire sitemap. I tried to resubmit the sitemap multiple times to both Bing and Google Search Console but that didn’t fix it. I uninstalled and reinstalled Rank Math, I changed the Links Per Sitemap limit, nothing works.
