I tried setting up wamp server to do a Quickstart install. I've been using wamp fine for some of my other Joomla installations. However, Joomla is now requiring PHP7 and so I tried upgrading from PHP5.5 to 7 and seemed to break my installation. I created a new directory on wamp and reinstalled Quickstart after going back and selecting 5.5 and I'm still getting a Whoops error. I'm sure I've made a mess but I can't get the front end to display anything but the attachment.

Whoops\Exception\ErrorException thrown with message "Maximum function nesting level of '100' reached, aborting!"
