Support » Plugin: HandL UTM Grabber » PHP Warning: Cannot modify header information – headers already sent

  • Resolved labatt


    I see you’ve responded to similar threads saying it’s not your plugin. However, I’ve narrowed this down to being a conflict with wp-cron. Every time wp-cron runs, it shows a conflict with this plugin about the header information. This only started after installing your plugin (which is an appreciated plugin). Is it possible you’re sending a whitespace somewhere in your plugin? I’m looking through the rest of the plugins I have to see if any others show anything.
