My Visual Editor is missing with some plugins

After locking myself out of my own site trying to change my wordpress/site URL. I followed instruction I found on http://codex.wordpress.org/Changing_The_Site_URL I hard-coded my url http://www.point2living.com into the site itself through wp-config.php.

I managed to get myself back into my site but now Some of my plugins seems to be corrupting my visual editor. The plugins I cannot activate (otherwise my editor for my posts cannot be found. I see only title and featured image).

The blogs are still showing on the front end but not on editor.
Plugins not compatible include: Jetpack, gocodes, and feedweb. I desperately need my gocodes plugin otherwise many of my outbound links won’t work!

Please help. I am not a programmer so would appreciate simple language.
