UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Member Search

I'm running UBB 6.7.0

Whenever I attempt to search for members via Control Panel / Member Management / View-Edit Members, the result is always the same~

"No members matched the criteria you entered. Please try a more general query."

The user names I am serching for are known current members.

Thank you in advance for your help!
