I hope someone might be able to help with this. A week ago we had a severe drop in rankings on the home page only. When I went to Google Search Console a new error was reported 2 days before the drop. The first was xmlrpc.php was returning a 405 error and wp-admin/admin-ajax.php is returning a 400 error.
I am looking at fixing the errors now, but one advice I saw on another site was to replace the xmlrpc with one from a fresh wordpress download. My question is, will this mess up a website?
any advice to get around the other error would also be much appreciated. Thanks
This all seems to of happened when a plugin was updated (Toolset Types) but the site is built with this so I cannot disable that particular plugin.
Many thanks in advance.
