I have a website offering subscriptions to use my tools. I am having an issue where my script isn't updating users subscriptions start/end dates.
For example, a users registers for a day subscription (day sub for testing, this will be removed for monthly sub)
First day of buying the sub:Subscription Start: 2024-09-06 16:36:14 (Y:M:D)Subscription End: 2024-09-07 16:36:14 (Y:M:D)Next Billing Date: 2024-09-07 06:00:00 (Y:M:D)
Next day when the sub runs out and re-news:Subscription Start: 2024-09-07 06:00:00 (Y:M:D)Subscription End: 2024-09-08 15:20:42 (Y:M:D)Next Billing Date: 2024-09-09 06:00:00 (Y:M:D)
as you can see the sub run out before the "Next Billing Date", i'm really not sure how to fix this issue or i'm doing this in the totally wrong way, any help is much appreciated
sub_update.php - runs every hour on cron
