All of a sudden I get this error when trying to add a new view: Fatal error: Class 'ViewsUiBaseViewsWizard' not found
I can edit existing views.

I have tried the Registry Rebuild module but that did not solve the issue.
I have tried to clear the Views cache and have disabled the cache which also does not help.
I have tried disabling and enabling the Views UI which also did not help.

All the modules are up to date.

I've got the same error, here. Freshly installed Drupal 7.22. I've only installed the following modules:

Chaos tools 7.x-1.3
Views 7.x-3.7
Views UI 7.x-3.7

And the aggregator module has been enabled. That's it. Tried uninstalling and reinstalling and clearing the cache. Not sure where else to look.

Oh, and yes, I've checked that my user is authorised to access Views :)

My site has developed the same error recently. I haven't tried creating a new view for some time, but it was previously working during development and the only changes made recently have been module updates.

I've got the same error, Fatal error: Class 'ViewsUiBaseViewsWizard' not found in...
I disabled Views & Views UI modules, then uninstalled the views module (deleted views from modules folder) (+then clear all caches).
Reinstalled views module (+clear all caches) and then the problem was solved.
