Do you have the latest Reborn version?
After typing patchver in the console you should see this:
Internal Version Number: 1.116
This is the newest version.
Also, are you renting your server and if so, who is your hosting provider?
Some hostingproviders use a bad setup, causing some Reborn functions not to work properly.
