Good afternoon. I just can not beat the problem.
Incorrect http header content-type: “text / html; charset = UTF-8” (expected: “application / xml”)
The error occurs only /sitemap_index.xml
In others, I did not notice this.
I disabled all plugins, themes, the error does not change.
But I tracked what the problem was. I have Hummingbird plugin installed, as soon as I clear the cache and check the validation, everything shows without errors,
should I go to the site map and refresh the page, re-checking the validation says that there is an error. If you clear the cache and disable this plugin and refresh the site map page, then there is no error.
Here’s what to do, this plugin significantly speeds up the loading of pages by pagespeed.
For earlier grateful, with respect, Max!
