Error after successfull patch SUPEE-5994: Class 'Mage_Install_Controller_Router_Install' not found

Question

I successfully installed the SUPEE-5994 patch :

[root@x]# sh PATCH_SUPEE-5994_EE_1.14.1.0_v1-2015-05-14-05-05-02.sh
Checking if patch can be applied/reverted successfully...
Patch was applied/reverted successfully.

But now, all my webpages are blank.

The httpd error log :

[error] [client x] PHP Fatal error: Class 'Mage_Install_Controller_Router_Install' not found in /var/www/x/public_html/app/code/core/Mage/Core/Controller/Varien/Front.php on line 138

I've tried to :

• Clear the /var/cache
• Reset the chmod / chown
• Restart the httpd service

But nothing seems to work.

Anyone have the same issue ?

EDIT: The Front.php file :

 Varien_Profiler::start('mage::app::init_front_controller::collect_routers');
    foreach ($routersInfo as $routerCode => $routerInfo) {
        if (isset($routerInfo['disabled']) && $routerInfo['disabled']) {
            continue;
        }
        if (isset($routerInfo['class'])) {
   // LINE 138 HERE
            $router = new $routerInfo['class'];
            if (isset($routerInfo['area'])) {
                $router->collectRoutes($routerInfo['area'], $routerCode);
            }
            $this->addRouter($routerCode, $router);
        }
    }
    Varien_Profiler::stop('mage::app::init_front_controller::collect_routers');

Answer 1

Have you switched off and cleared compilation?

via the console/ssh you can use

$ php -f shell/compiler.php -- disable

$ php -f shell/compiler.php -- clear

$ php -f shell/compiler.php -- compile

$ php -f shell/compiler.php -- enable

might need the fourth line...not sure.

It might be a problem with the line that comes before the code you showed

$routersInfo = Mage::app()->getStore()->getConfig(self::XML_STORE_ROUTERS_PATH);

Note: I had a similar problem where the admin was blank, however that turned out to be a file in a module that was overriding one of the core files - but this is not in your case. Just in case others look at this with that issue.

Answer 2

If you've disabled the compiler and cleared the cache and you still run into the error

Class 'Mage_Install_Controller_Router_Install' not found

Check to see if the file app/code/core/Mage/Install/Controller/Router/Install.php exists.

When you ran the patch, the directory Router didn't exist in app/code/core/Mage/Install/Controller and so the Install.php file did not get created despite being told otherwise in the applied.patches.list file. This means you're missing a class and you get the message:

Fatal error: Class 'Mage_Install_Controller_Router_Install' not found

Excerpt from the applied.patches.list for the supposedly successful patch installation that fails to create the Install.php file:

patching file app/code/core/Mage/Install/Controller/Router/Install.php
patching file app/code/core/Mage/Install/etc/config.xml

The patch creates the following addition to the app/code/core/Mage/Install/etc/config.xml file which references the missing file:

 <default>
     <web>
         <routers>
             <install>
                 <area>frontend</area>
                 <class>Mage_Install_Controller_Router_Install</class>
             </install>
         </routers>
     </web>
 </default>
 <stores>
     <default>
         <web>
             <routers>
                 <install>
                     <area>frontend</area>
                     <class>Mage_Install_Controller_Router_Install</class>
                 </install>
             </routers>
         </web>
     </default>
 </stores>

Sample of what the missing file app/code/core/Mage/Install/Controller/Router/Install.php is supposed to contain.
