i just find appropriate solution for this problem ..
just nothing
step 1. ensure that there are no duplicate file here like extra phpmyadmin or php version don’t exist with each other
step 2. total remove if there are another server exist…
step 3 .if fully remove all thing then again install a server
hope it won’t be show this warring….
enjoy
