PHPMailer not working on my website

Hi! I need help I really need to deploy my system soon and now when I try to implement it on this hosting it got messed up in the emailing service that it performs.

Here is my situation:

  1. I use phpmailer and gmail as smtp.
  2. All scripts are working in local host but got messed up when uploaded on the hosting provider.
  3. I’m only using freehosting now to test my system.

Here is my site:

https://matrilocal-meets.000webhostapp.com/

I hope you can help me to get this emailing service working ASAP :frowning:

Do I need to upgrade just to make this work? or there is something wrong with my code?

P.S There is no error messages it just work normally but doesn’t send the email.

Upgrading would resolve it as the paid service is premium.
The issue stems from the free service being abused and blacklisted
