The settings page is just blank

Quickly check by disabling all plugins to see if any plugin is causing the issue and deactivating and reactivating theme. If it works then enable plugin one by one to rule out issue causing plugin.

If that doesn’t help then,

Please email us ([email protected]) the following details:

– Which host?
– WordPress and PHP version
– Are you using a non standard WP install, for eg. different sub directory install?
– WP Login details for inspection

Update: Resolved via email

For reference: It was WordPress configuration issue of missing auth salt key:

Notes:

The issue is due to an old WordPress install.

The key/salts (in this case auth key) are not updated in wp-config.php

To resolve:

wp_salt()

The following generates salts on each refresh, just copy and paste in wp-config.php ( login via ftp to get to the file )

or try this plugin https://wordpress.org/plugins/salt-shaker/
