The exact thing that happens is that the page stops loading like it would once the .pdf file opens, but no .pdf file opens up. I cannot get the tickets from the user or administrator end. Like I said, this only occurs on ticket orders of 10+ tickets. It also occurs on Cash-Desk purchases of over 10 tickets

Hello,

What version of E-Tickets do you have installed?
And it stops loading means that you see completely no ticket and tickets are only broken?

Version - Joomla Extension 2.1.1
The page just stays blank with the URL on the top. Usually, when working correctly the page loads, to a blank page, and a .pdf file opens from which I print the tickets. What happens here is that that .pdf file never opens nor downloads.

Can you check log files if there are any errors?

Maybe it is stopped on maximal_execution_time. Or there can be problem with font that if you print ticket where is used special character, then final pdf is blank. I hope, logs will say us more.

It looks like the Maximal Execution Time was exceeded, it was set at 30 seconds. I recreated the issues and posted the Error Codes below. What should I do to fix this issue?

I have also had a lot of these warnings that I noticed on the Error Log file. I think there might have been an issue earlier on that occured every once and a while. I haven't seen it too recently but it could still be happening.
