Event Calendar 3.1.4 conflict?

A couple of weeks ago, my site got a not found error on every page and no posts appeared in wp-admin. After original concerns that it was my database, I determined that it was a problem with Events Calendar 3.1.4.
Every time I activate events calendar, I get the not found error. If I deactivate it all of the posts show up.

I tried reinstalling it, but I’m still having the same problem. Originally, I had an error log, but I deleted it and it isn’t generating a new one.

Thanks in advance.
