zend framework - Fatal Error Zend_Uri Magento -

-

suddenly our magento store has fatal error:

php fatal error:  class 'zend_uri' not found in /.../public_html/app/code/core/mage/core/model/store.php on line 726

no new plugins or modules have been added recently. compiler not active, var/cache , var/session empty. permissions resetted magento folders / files.

no other errors or more information provided, have blank page - on frontend , backend.

magento version 1.7.0.2. appreciated.

line 726 of store.php file looks this

#file: app/code/core/mage/core/model/store.php  $uri = zend_uri::factory($securebaseurl);

that is, magento's making call static method factory on zend_uri class. error

php fatal error: class 'zend_uri' not found

indicates php can't find zend_uri class. because

  • the class definition file no longer there,
  • someone has changed class definition file it's no longer valid
  • a local code pool override file exists , has edited class override file it's no longer valid
  • someone has edited lib/varien/autoload.php can't load zend_uri class file
  • a local code pool override file exists varien/autoload.php , has edited can't load zend_uri class file
  • someone has changed php include path (normally defined in app/mage.php) doesn't include lib folder, or code pool local code pool override might exist

i'd start looking zend_uri class in lib/zend/uri.php, , work way down list until figure out why php isn't autoloading class file.
