Hey Matty,
Thanks for reaching out and sorry to hear about this issue you are experiencing. I’ll help you getting this right!
Can you please follow the steps described in our Testing for conflicts guide? This way we can see if this is a problem in our plugin or a conflict with the theme or other installed plugins. It would be great if you could share your system information with me so I can check if everything looks right on that end (you cna mark your reply as private if don’t you want the sys info to be public).
I’ve just tested this locally but wasn’t able to re-create the issue, I can submit events without being logged in. Any particular steps to generate the error?
Please let me know about your findings so we can continue to work on this,
Best,
Nico
