how to fix magento 2 front controller reached 100 router match iterations


This error will be shown when Magento cannot find a proper route for a request. Your routers start making infinitive references for dispatching requests.

In general, it should be able to match a request with the router that handles requests. The exception is only triggered when Magento has failed to create routers, and then the error Front controller reached 100 router match iterations will be displayed.


In app/code/core/Mage/Core/Controller/Varien/Front.php inside of the dispatch() function. The following code snippet will give you an idea:

while (!$request->isDispatched() && $i++<100) {

    foreach ($this->_routers as $router) {

        if ($router->match($this->getRequest())) {





Replace the code above with:

Mage::log('----Matching routers------------------------------');

Mage::log('Total ' . count($this->_routers) . ': ' . implode(', ', array_keys($this->_routers)));

while (!$request->isDispatched() && $i++<100) {

    Mage::log('- Iteration ' . $i);

    $requestData = array(

        'path_info' => $request->getPathInfo(),

        'module' => $request->getModuleName(),

        'action' => $request->getActionName(),

        'controller' => $request->getControllerName(),

        'controller_module' => $request->getControllerModule(),

        'route' => $request->getRouteName()



    $st = '';

    foreach ($requestData as $key => $val) {

        $st .= "[{$key}={$val}]";


    Mage::log('Request: ' . $st);

    foreach ($this->_routers as $name => $router) {

        if ($router->match($this->getRequest())) {

            Mage::log('Matched by "' . $name . '" router, class ' . get_class($router));





The error log to be generated var/log/system.log.

Or you can also add the following debug code to app / code / core / Mage / Core / Controller / Varien / Front.php: Line 183:

if ($i>100) {

        file_put_contents('/tmp/debug.txt', Mage::getConfig()->getNode()->asNiceXml());

               Mage::throwException('Front controller reached 100 router match iterations');



  • If you found the error in the admin section, let’s change the admin URL in app/etc/local.xml to fix the problem. Replace urltoadmin value with the URL you want and your new admin URL should be:








  • CMS module disabled: As you might know, the CMS module handles 404 not found requests which is the fallback router. Therefore, no router may be found in case this module is disabled.  Just enable the CMS module and check if the issue is solved.
  • The cache is corrupted: This is another common cause – Magento cache corrupted. In this case, the list of routers never gets loaded because it loads from the cache and the corrupted cache does not contain this data. Consequently, fully flushing the Magento cache will resolve this issue. You can also delete /var/ cache folder to remove cache corruption.
