Getting Kicked out of Admin since latest update

Hello again,

I recently updated a couple sites I'm working on to the latest Perch release (3.0.11), and ever since the update I'm continually getting kicked out of the admin panel.

Each site is on a different server, (one is running on my development server, and one is on my production server) and running a different version of PHP. One site is running Perch and the other is running Runway. I didn't have this problem on either site before the most recent update.

I'm wondering if anyone else is having this issue, or any insights.
