We have purchased a simple php-mysql helpdesk script but the developer who did this job is no longer available and is not supporting the script. The script uses plain php-mysql, no frameworks, etc.
We like this script and we want to continue using it, but there are some bugs that needs to be fixed and some additions that we want to make.
We will sent you the script as well as a working demo to see how it works. Also, we have prepared a list of the tasks that needs to be done.
Send me a pm and I will give you more details.
