When I try to update to version 6.3.2 the zip file downloads and says that it installed then tell me to reboot my server.  Then when I reboot my server it come back saying the it is still version 6.2.2 like nothing happened and still tells me the I need to update.  I am hoping that someone knows how to fix this problem.  Thanks for you help.

Try it again, but before you reboot, Tools - Diagnostics and post here

 

Are you updating from the Plugins page? I would have thought it would update to 6.3.5 (latest stable) instead of 6.3.2. Maybe you need to check for updates on the plugins page if it is telling you the latest is 6.3.2
