2 years ago There is no timeout.
There's no problem with multiple payments at once, each is in it's own session and is seperated from the others.
If you could make a pull request with the changes that would be helpful. I looked but can't find the issues you mentioned.
I run WHMCS in a /billing sub directory. This breaks a few links within the code. Simply adding a "system url path" variable before the links resolves it.
Also, there is an additional "/" in the link to createinvoice.php , simply removing it cleans up the url display (it still works without this fix obv).
Other than that I just tested this code as working on the latest WHMCS.
Two questions, is there a timeout on the invoice display at all? ...and how does this set up handle multiple people trying to pay at once? Is there no conflicts when 4-5 people try to pay an invoice at once for example?
Anyway, thanks a lot for writing this code!
