Please remember that this is a publicly accessible forum, so never share any sensitive data (like passwords) here. I just reset your account password.

As for your code, maybe the cutt.ly API is slow and preventing the successful execution of your code? Does the API call have a timeout set?

[HaydenANG]

Can you try instead of <? use <?php

@HaydenANG Yess

[_aw_techy]

First thank you so much for step and I’m really Sorry that I mistakenly shared my password, and I’m changing api from Cutt.ly to another.

[HaydenANG]
