How to fix :Sorry, we can’t log you in. Unable to read the WordPress site at that URL
Before we start to we uninstalled or SA We disable pluginLet's see if there is no conflict with the application, we must understand how it works and what are the vital elements for the proper functioning.
When we want to We connect an application to a website created with WordPress, we must consider DRAGE DATA TRANSPORT PROTOCOL, from WordPress to the rective application (in our case, the WordPress application for iOS). The transport protocol is done through XML-RPC.
When we meet an error of the form of the one presented by us, we must consider two essential things:
1. Let's make sure that on the server hosting the website, the file xmlrpc.php are Permissions (chmod) reading for “user“, “group“, “world” and belongs to the group (Chown) of law. We can check this by accessing in the browser domain.tld/xmlrpc.php. “XML-RPC server accepts POST requests only.”, is the message to be displayed in the browser.
2. In our case, the problem was a little more complicated. I could not add a website in the WordPress iOS application, because there is no XML module for PHP on the server.
Like a script PHP to be able to run a line XML, it is necessary that on the server be Installed the XML module for PHP. Otherwise the WordPress application will give the error “Sorry, we can’t log you in” Every time we try to add a website.

How to view PHP modules installed on a web server (Centos, Ubuntu, etc.)
We execute the command line in the terminal: PHP -M
If in the list of modules do not appear: xml,xmlreader andxmlwriter, then be sure that this is the cause from which you cannot add a site to the application WordPress for iOS or Android.
How we install the XML module for PHP on a web server
Centos command line:
yum install php-xml
After installing the PHP-XML module, restart the services: PHP / PHP-FPM, httpd / nginx.
Add the website again to the application, and everything will go smoothly.
Ps. The installation of the PHP-XML mode can only be done by the server administrator. If you are not the server administrator, contact and ask the web hosting supplier to install or activate this module.
