 * Hi there,
 * I’m getting this message a lot these days (across various WP sites):
 * ‘Unable to communicate back with site to check for fatal errors, so the PHP change
   was reverted. You will need to upload your PHP file change by some other means,
   such as by using SFTP.’
 * Can we please have a function to disable this error check? I don’t need it if
   it’s going to prevent the file saving.
 * I see various posts about turning off plugins, checking host config etc to get
   it working but surely that’s a very cumbersome workaround, the editor should 
   not be rendered useless by rogue plugin behaviour.
 * Cheers,
    Sam

 * Also SFTP is not ideal when multiple people are working on the same site as you
   run into sync issues, hence it would be nice if this worked as it used to. Thanks

 * Please install the health check plugin
 * [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)
 * It can run a test and figure out what plugin is breaking your loopback ability.

 * Hi Steve,
 * Thanks for getting back to me, I’ve installed the plugin but it seems like the
   loopback functionality is intact ‘ – The loopback request to your site completed
   successfully.’
 * Any ideas?
 * Cheers,
    Sam

 * Are all directories writeable?

 * All good now, just found the issue to be the ‘password protected’ plugin, I had
   an IP restriction set there because the site is in development which must block
   the check somehow.
 * Thanks for your help
