At first glance, this does look like it might be a conflict with Postman, but Postman is a plugin that lets you configure an SMTP server for email, which doesn’t seem like it would be related to anything with WordPress Feeds. * Can you tell me how this error was generated? Was the error the result of some action, or did you just see it appear in your error log? * Also, this path doesn’t look complete: * `#6 /home/wp-content/plugins/postman-smtp/Postman/Postman-Email-Lo` * Is there anything that comes after `/Postman-Email-Lo`? * Thread Starter [massimod](https://wordpress.org/support/users/massimod/) * (@massimod) * [9 years, 6 months ago](https://wordpress.org/support/topic/php-fatal-error-uncaught-error-2/#post-8455424) * Hi ! * The #6 is correct, i did some edit to remove the domain in all above lines, i missed this one. But here it is again: * #6 /home/wp-content/plugins/postman-smtp/Postman/Postman-Email-Lo in /home/valuema/ valueweb.gr/wp-includes/link-template.php on line 588 * Nothing else. * Also i have no idea when it happens. I just saw it today several times in my error.log. The omly difference in the errors is * do_action(‘clean_post_cach…’, 734, Object(WP_Post)) * This started as number 729 and rises …. * Since i haven’t changed/added anything (posts etc etc), i can only guess it happened during some update of plugin or something like that. Maybe it is not even Postman but something else. * I will try this weekend to find more and update here. * Thread Starter [massimod](https://wordpress.org/support/users/massimod/) * (@massimod) * [9 years, 6 months ago](https://wordpress.org/support/topic/php-fatal-error-uncaught-error-2/#post-8455460) * More information: I manage several WP sites and i see the same error in ALL that use Postman. 2-3 that don’t, are error-free. * So definitely is something with Postman. * I hope i have helped ! * Thanks ! - This reply was modified 9 years, 6 months ago by [massimod](https://wordpress.org/support/users/massimod/). * [Raam Dev](https://wordpress.org/support/users/raamdev/) * (@raamdev) * [9 years, 6 months ago](https://wordpress.org/support/topic/php-fatal-error-uncaught-error-2/#post-8458666) * [@massimod](https://wordpress.org/support/users/massimod/) Thank you for the updates.
