I am working on a site: greatlakesecho.org When I try to edit a post, the content just disappears from the visual editor. I am running the latest version of Word Press but this happened on the previous version as well. I am using the Project Largo theme with the site.
The site was recently migrated from to a new host and has gone an overhaul into a responsive design. This first started happening when I changed the character encoding to remove odd symbols from the posts. I was successful in that by changing it to utf16. At this point only older posts that were created before the migration would disappear when I clicked edit. I have since updated to the latest version of Word Press and it happens to every post.
I've already made sure the wp-config has the correct encoding.
It happens with all themes.
Tried deactivating all plugins.
I also see this when enabling debuggin:
WordPress database error: [Table 'greatlak_wp776.wp_itsec_lockouts' doesn't exist]
SELECT lockout_host FROM wp_itsec_lockouts WHERE lockout_active=1 AND lockout_expire_gmt > '2014-04-22 19:52:36' AND lockout_host='35.9.132.246';

edit: Extra Info
I had to remove the Navis Media Credit plugin manually. I searched through the plugins folder using WinSCP and apparently when I was removing all the plugins using the WordPress admin panel, this one wasn't actually getting removed. This plugin was conflicting with the theme I am using and I learned this by deleting all the plugins and using one of the default WP themes.
