Enabling Views module causing cron to fail Quite simply, I enable the super common "Views" module, and on Save nothing but a white page happens. 
On a refresh (Where I agree to the form resubmission) the modules page comes back just fine.  

Then I click the "Run cron" link, and that is also blank, and never shows anything else or redirects. 

Visiting cron.php by itself, also blank. 

I've seen some solutions, such as increasing php's memory_limit and mysql's max_allowed_packet, but neither have done anything. 

Everything runs optimally again the moment I disable Views. 

Some info:  

Web server: nginx/1.4.6
PHP: 5.5.9
PHP memory limit: 256M
Drupal: 7.35  

I've never had this problem before, especially with Views
Sounds like either:


You have two copies of the Views module enabled somehow.
You have a problem with your server configuration in relation to op-code caching.


Check your "system" table in the database with:

SELECT name, filename, status FROM system WHERE name = 'views';


Check the results are as expected for your install.

For the op-code cache issue, check this thread:


  Cannot redeclare class view, updating to PHP5.5

It may be a problem with using multiple op-code caching methods, or xcache conf issue.
