 * Hey there,
 * Sorry to hear that. Could you please let me know:
 * – What version of WP Car Manager are you using?
    – What version of WordPress 
   are you using? – What version of PHP are you using? (you can check this with 
   your host if you don’t know this).
 * Cheers,
    Barry

 * Hey,
 * Do you mean `WP 4.5 MU` it’s a Multisite/Network installation?

 * Hey,
 * This is most likely a Multisite related issue as MU tends to handle certain hooks
   differently. I’ll try to look into this for version 1.3.0.
 * Kind Regards,
