Hi Mat!
Thanks for reaching out to us!
I’m not really familiar with ListingPro, but we work hard to make our plugins broadly compatible. However, like all WordPress developers we cannot test with every plugin, theme, and server environment out there. So the best way to ensure full compatibility with other plugins and themes is to setup a dev/staging site so you can test things out.
I want my users (people that create listings) to be able to create and sales tickets for their own events. Is that possible ?
I recommend you take a look at our Community Tickets plugin that works alongside our Event Tickets and Event Tickets Plus plugins and will enable a frontend event submission form.
Is there a way to get all those features for a trial period and buy it after ?
Unfortunately, we don’t offer a trial period, but we do have a pretty cool refund policy so you can test our plugins and in case they don’t meet your needs you can ask for a full within 30-day of purchase.
I hope that helps. Let me know if any follow up questions.
Best,
Victor
