Ticketor

Ticketor is a full-featured event ticketing and box-office solution. You can use this plug-in to add event ticketing and box-office features to your WordPress site.

Please note that this plug-in is just a light-weight shell container and does not require updates. It easily works with newer versions of Word-Press. As a result you may not see much updates on this plug-in. However Ticketor is well maintained and gets updated very frequently.

To use this plug-in, you need to sign up for a Ticketor account, then use the plugin to embed a specific page or feature to your WordPress website.
To sign up, simply go to https://www.Ticketor.com , click on sign up, provide your basic information and you will get a ticketing and box-office portal immediately, where you can create and manage your events.
As part of the portal, you will get a page that lists all your upcoming events and one page per event and other optional pages.
You can embed any of those pages in your WordPress website.

To embed a page, go to that page and then from the “Control Panel > Settings tab” select the “Embed” option. You will be provided the short-code to use in WordPress. There are a few options there that you can customize the behavior and the shortcode.
