Error opening Roundcube

[TGates]

I'm not sure what has caused this issue for you, but I have found this:
(Always make a backup!)

./program/js/app.js (replace app.min.js with this):
Code Select Expand

Code:

    // clickjacking protection
    if (this.env.x_frame_options) {
      try {
        // bust frame if not allowed
   
        if (this.env.x_frame_options == 'deny' && top.location.href != self.location.href) {
          top.location.href = self.location.href;
        } else if (this.env.x_frame_options.indexOf('ALLOW-FROM') == 0) {
   
        } else if (top.location.hostname != self.location.hostname) {
          throw 1;
        }
      } catch (e) {
        // possible clickjacking attack: disable all form elements
        $('form').each(function(){ ref.lock_form(this, true); });
        this.display_message("Blocked: possible clickjacking attack!", 'error');
        return;
      }
    }
