Problem adding products

Can someone tell me why I would get this message?

Front controller reached 100 router match iterations

[Tom Robertshaw]

Do you have any custom extensions installed?

Sometimes this can happen in Magento 2 with a bad router (https://magento.stackexchange.com/questions/135532/magento-2-ce-front-controller-reached-100-router-...

Check your routes.xml file

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="standard">
        <route frontName="helloworld" id="helloworld">
            <module name="Magento4u_HelloWorld"/>
        </route>
    </router>
</config>

where frontName shoud be a unique name.

id should be a unique name,

Module name should be your <Namespce>_<ModuleName>
