What you are seeing are warnings and notices. This is most likely because you are now running on a newer version of PHP, running in Debug mode.
The PHP foundation software has advanced much more quickly than the Tickets code base. If you choose to install an older php version, you'll see fewer warnings, but find there are no longer any security fixes available.
I'll update sourceforge later this weekend when I can find the time.
Tim,
I'm going to assume you are running your installation right now on WAMP which by default has a debugger enabled. WAMP was designed for developers to test their software at their local PC before moving to a server or the cloud to host their applications. You may want to disable debugging to minimize the various warnings.
https://www.google.com/search?q=wamp+disable+debug+modeYou'll have a better user experience than seeing the constant reminders that PHP has left behind the methods of the past decades. Tickets is still improving, but it's years behind the current state of PHP.
I do understand your frustrations. However, I'm not able, as a single volunteer, to investigate issues with older versions that very possibly have already been fixed. I think if you can update to the newest version, and if you can disable debug mode, You'll have a far better experience for your users. I do definitely want to hear from anyone running the latest version, of any code improvements or bug reports.
I'd beg everyone to please complete the survey. To give some perspective, I can count the number of people using tickets, based on the survey, on my hands! Yep, less than a dozen. This does put a damper on the prospects of me taking another couple weekends of more coding to update things again.
