I'm having an issue with the debug mode being displayed by default. I went into the config section and unticked the box in the Maintenance section. Gallery I'm having issues with is: https://bellaramsey.org/gallery and I'm running the latest stable version of 1.6.25.

Solved it. Debug was enabled in phpmyadmin database. Logged in and clicked on gallery table. Then found debug in search, changed the "1" to a "0" now no notice is displayed. Don't know how it got turned on in the first place. Unless asked I don't display debug notices.
