Hi, in many hosts, such as apache mod security or other security systems, they protect xmlrpc.php, so it is better to use your mobile web browser for posting.

If you want fix your problem, say your host type( apache or…), And all secuity plugins are active.

Refused to apply style from ‘https://secureservercdn.net/198.71.233.44/ajt.bd5.myftpupload.com/wp-includes/css/dist/block-library/style.min.css?ver=5.3&time=1573813584’ because its MIME type (”) is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Please add type to your css files.
Set MIME type as type="text/css",

<link rel="stylesheet" type="text/css" href="yourstyle.css">

Next add this line into your htaccess (litespeed & apache only):

Header Always Set X-XSS-Protection "1; mode=block"
Header Always Set X-Content-Type-Options "nosniff"

Then, recheck.

Dear users, please use manual update if you can’t update automatically.

See here:

You can do it with cpanel:

1. Simple copy wp-content & wp-config.php to a directory out of public_html (for example, create a folder by name “backupold” and put files in it)
2. Download latest version
https://www.ads-software.com/latest.tar.gz
3. Upload it in your wordpress directory (output file will be in public_html/wordpress for example)
4. Copy (backuped contents) “wp-content” folder & “wp-config.php” file to “wordpress” folder & replace
5. Move all files and folders from “wordpress” folder to your site directory (by default, public_html) & replace.

Now enjoy!
