New Install Doesn't Record Traffic

I’m new to piwik and have a fresh install of Piwik v 2.16.2 which stopped recording traffic after installing a few plugins. I added about 10 and have deactivated/uninstalled them. Which didn’t fix the problem.

I’m getting an error showing when I navigate to a page and look at the console errors:

"http://<>/piwik.php?action_name=Name&idsite=2&rec=1&r=438332&h=12&m=20&s=57& to load resource: the server responded with a status of 400 (Bad Request)

Piwik isn’t getting any data from traffic, including visitor info.

Any suggestions?
