based on this guide after following all the steps i was excpecting to see the QR code screen so i can register my Google Authenticator. https://gluu.org/docs/ce/authn-guide/otp/ what i got is the error on the title when i ran the https://[My_Hotname]/identity/register as recomended from the guide i got back to the main page of Gluu with an error message Faild to execute registration scirpt. please contact site administrator i am new to Gluu and the guide seem to be easy. did i forget to give some privliges to the script folder and that is why the scripts are not able to run? Thank you
