 * Hi Mohammed,
 * Did you added the correct authorization password that is generated from the mpgs
   admin?
    At what screen you are receiving the above error?

 * Hi,
    I have the same issue, yet I used the authentification password proposed
   by mgps admin. This error occurs at checkout. Would you like credentials so you
   can see ? Thanks

 * Hi [@reemmoussa22](https://wordpress.org/support/users/reemmoussa22/) , [@samuraiwebexperts](https://wordpress.org/support/users/samuraiwebexperts/),

 * Please make sure to use MPGS API version 49 as it is the most tested version.
 * You will get this error whenever you set the MPGS API version to anything above
   50.
 * I published the plugin version 1.2.0 recently, make sure you are using the latest
   version of the MPGS plugin.
 * Thank you for using it 🙂
