In my case, I’ve been able to fix this issue by checking the chrome console.
I’ve found that one of my options was used to save javascript code (adwords, olark, etc) and while this was working fine on localhost, at the staging server it was producing an error:
The XSS Auditor refused to execute a script in xxxxxxxxxxx/wp-admin/admin.php?page=XXX-theme-settings because its source code was found within the request. The auditor was enabled as the server did not send an 'X-XSS-Protection' header.
Si I’ve removed any javascript contents and started working again.
I’m wondering if there is some kind of workaround for this?
