Hi Sonya,
this is a known issue that we’re working on a fix for. Thanks for your patience.
You can track progress on this (and other bugs) on our 3.11.1 milestone
In the meantime, you might consider rolling back to the 3.10.1 release. You can do that using the excellent WP Rollback plugin or downloading it here directly.
Again, we apologize for the inconvenience this is causing you (and many others). We’ll get a fix out as soon as we can.
sonyalynndesigns,
If I could ask a favor – could you attempt to flush rewrite rules on your site and seeing if that fixes the issue?
You can do that by simply going to your Permalinks page under General Settings.
Let me know if that happens to resolve the issue (fingers crossed!)
Changing Permalinks did not fix this issue, I already tried that.
