Warning: array_flip(): Can only flip STRING and INTEGER values!

After updating Event Tickets Plus to version 4.6.2 I get the next error when I want to export the data:

Warning: array_flip(): Can only flip STRING and INTEGER values! in /home/users/natmnftp/natm.nl/web/wp-content/plugins/event-tickets/src/Tribe/Tickets_Handler.php on line 288

Hi. Sorry you’re experiencing this.

I tried it on my local testing site and couldn’t replicate the issue. We also haven’t had reports from other users. Therefore, I’d suggest following our recommended troubleshooting steps:

There might be some new updates available. Could you please make sure all your Modern Tribe plugins (and WordPress core) are at their latest versions?

• Downloads / Version Numbers
• TEC Automatic Updates
• or TEC Manual Updates
• WordPress core updates

Once you verify you’re on the latest versions, please test to see if the issue is still happening for you.

If it is, please follow our Testing for Conflicts Guide (basically switch to TwentySixteen theme and deactivate all plugins and custom code other than Modern Tribe plugins) and see if that helps narrow down the cause of this.

If it doesn’t, please enable WP_DEBUG and WP_DEBUG_LOG and share any PHP errors you see while changing tickets quantity, navigating your site’s home page, events page, single-event pages, and any other of your site’s pages relevant to this ticket.

Then, please share your System Information (while in Testing for Conflicts mode).

You might also see if you can spot any console errors at your site. (If needed, you may reference our KB article Using Google Chrome Developer Tools.)

Let us know what you find out.

Thanks.

Hey there! This thread has been pretty quiet for the last three weeks, so we’re going to go ahead and close it to avoid confusion with other topics. If you’re still looking for help with this, please do open a new thread, reference this one and we’d be more than happy to continue the conversation over there.

Thanks so much!
