After updating to Types 3.0 I am not able to switch from Visual to Text view in the WordPress post editor. If I disable Types 3.0 plugin it works.
In console view this is shown even before I click the Text view so not sure it is related.
Uncaught TypeError: Cannot read property 'settings' of undefined (jquery.validate.js:119)

By the way the issue is not a plugin conflict. I have tested with only Types and Views activated and same issue.
This works perfectly fine on may installs (all I have seen until now) running either 2.2.23, 2.3 or 3.0 Types.
It must be a conflict or a corrupt file.
Please deactivate all Plugins, and use a native WordPress Theme.
Make sure WordPress is up to date, and replace the current Toolset Plugins with the fresh copy from your downloads area.
Does the issue now persist?
If so, I will need a copy of your site:

Tried reinstalling both plugin files and wordpress and the issue is now gone
