Our Wordpress site is moving very slow and we need someone to help speed the site. We believe part of the problem is that the site is having issues parsing html files.
We also are having an issue with a plugin we use "grabpress". We are getting an error when we go to the dashboard and need someone to see if the issue can be resolved.
Fatal error: Call to undefined method DateTime::sub() in D:\hosting\4513419\html\wp-content\
