 * Hello [@rocketrobin](https://wordpress.org/support/users/rocketrobin/)
    I recently
   was able to reproduce the issue: `Non-static method BackWPup_Admin::admin_css()
   should not be called statically`, will back to you shortly, and please no worry,
   this warning does not affect the backup feature of BackWPUp!
 * About another warning: `Deprecated: media_buttons_context is deprecated since
   version 3.5.0! Use media_buttons instead. in /home/rocketr6/public_html/wp-includes/
   functions.php on line 5152`
    The warning is not caused by BackWPUp but by other
   plugins, you can troubleshooting the issue by disable plugins one by one and 
   find which one caused the issue.

 * since we haven’t heard back from you, I’m going to mark it as resolved.
    If you’re
   still having problems, feel free to let us know 😉
