We have a popular niche adult website using ccbill payment processing.
We have currently have issues with users not upgrading properly once their rebills or payments are taken. It has worked for months but it is now intermittently broken. The website uses [url removed, login to view] software. The winning person must be very confident in fixing this as this is a live site with thousands of users daily. There cannot be any downtime or issues with users taking payments.
The project has two parts:
1) Fix ccbill upgrades so that they work consistently with no issues. Seems to be a cron job issue when the site moved servers. Programming is all done as it worked for months before that with no issues.
2) Integrate ccbill check and bank transfer payment options
Please do not bid if you are not very confident in fixing this quickly and efficiently without affecting current traffic and revenue.
You must be comfortable with niche adult websites.
