Cannot modify header information (on page reload)

I’m not seeing it on default WordPress, so most likely there is interference from some other plugin or maybe something the theme is doing. Best advice would be to do some basic troubleshooting. I would be glad to provide a guide if it might be useful for you.

Thanks very much for your?reply. I narrowed down the problem to the Blocksy theme and/or the Stackable blocks-library plugin. When I deactivate either one of those, I don’t get the error message on the User Submitted Posts form submission. If either or both of those are activated, I get the error. Would this be something that the Blocksy and/or Stackable people need to fix on their end?

Yeah it’s not something I’m familiar with so you might want to ask them why it’s happening etc. Also just in case it helps, it’s kinda rare for users to reload a form page while filling it out, before submitting. It does happen, but not sure how frequently.

@bjtalbot I hope you got this sorted. It’s been awhile with no reply so gonna go ahead and mark this thread as resolved to help keep the forum organized. Feel free to post again with any further questions or feedback, Thank you.

Good news / bad news: I got it sorted out! But only because the site owner decided we don’t need to allow front-end post submissions, so we don’t need the plugin. ??

Thanks again for your help!

Cheers!
