Hi, I have Osticket v1.6 ST with some modifications and I don't want to risk updating this versión.The issue I have right now is when someone submit a new ticket, the page start loading and last a bit, so clients insist on clicking the submit buttons, this creates multiple tickets and they get the limit ticket error message and I must delete manually the repeated tickets from the opened tickets list.I tried adding <onclick="this.disabled=true;this.value='Please wait...'"> to the submit button in open.inc.php but it stops working... Is there any way to do something like dissabling the button while page is loading? Please take in mind that I'm not an expert php developer.thanks in advance!
