My problem here is when I edit a post and click 'Preview changes', the changes do not take place in the preview. I deactivated all the plugins I have and activated those one at a time and at the same time, I also tried editing the post, preview changes and the changes took place. When I activated the plugin 'Exec-PHP', my problem starts there. By clicking 'Preview changes', the changes do not take effect in my post. This is actually the first time it happened because in the other sites I made, 'Exec-PHP' is activated and the 'Preview changes' works. Help?
