Hey @webgrain,
I see what you mean! That’s definitely not expected behavior. In fact, I was unable to get the same thing to happen on my own test site when using a default WordPress installation.
I see you tried deactivated all other plugins. Did that have any effect? The next thing I would try is switching to a default WordPress theme–actually it would be a great idea to walk through the steps outlined in this troubleshooting guide in full. That will help explain why the search would reset on your site but not when I try it on my test site.
In the meantime, it would also be super handy to have your system information. If you head to Events > Settings > Help, you an copy the information at the bottom of the screen and paste it here as a private reply. That will help me look for possible red flags and go even deeper to try to recreate the issue myself.
Let’s start here and see what we find. 🙂
Thanks!
Geoff
