What version are you on and did you recently upgrade or downgrade? 

The creating/adding message should only appear once and happens when you have a schema file in /data/schemas/ that doesn't have a MySQL table for it.  The CMS is trying to recreate the missing tables that are defined in your schema files.

As for the login expiry, if clearing your cookies doesn't work feel free to send in a 2nd level support ticket here and we'll take a look:

No changes were made to the server or the website. I did a restore and still have the same issue.

I can login via cmsAdmin but I'm unable to navigate any links within the CMS and receive the following message:

"You've been logged out due to inactivity, please login again to continue."

Any help would be appreciated
