As I said..Where you place the code that comes to the contenidopago???
How to make it work:
1. You can disable it in pages/buypoints.php
2. Config is in 'custom_scripts/contenidopago/config.php'. Set valid (same as in config.php) URL to report script when you register 'tibia auto' on contenidopago page. After registration of 'tibia auto' you will get ID of service. Copy it to config in 'custom_scripts' and set same amount of points for SMS on contenidopago page and in config.php of contenidopago.
For some users it shows white box, not box with informations how to pay. It's contenidopago bug, but if it works for you, it will ask you about account name and then it will show what text to what phone number you must send. If you did configure it fine in acc. maker it will add points to your account automaticlly [amount of points you configure on contenidopago.com, not in acc. maker!!!] and send you SMS 'you received points.' (I did not test, but guy from contenidopago said it works that way). If acc. maker is configured wrong or you set wrong 'report url' on contenidopago then you will receive SMS with code that you must enter in form on acc. maker page.
