Hello,

If you disable this does it resolve the issue?

Thanks,

Trevor

i have disabled this option but the issue cannot resolved!

Wow, i find that when i uncheck option "Use OLD_PASSWORD Algorithm" and click Update, Solidcp seem doesnot know that change. The Option still there

Wow, I have unchecked option “Use OLD_PASSWORD Algorithm”  and clicked Update by Filling with the root password of MySQL(before i don't fill the root password)...and Solidcp successfully connect to MySQL Server for creating user DB and GRANT permisson USAGE for that DB .

Thanks Trevor Robinson's suggest!
