What steps will reproduce the problem?
1. install and activate wp-diso-profile plugin
2. install and try to activate wp-diso-contactlist plugin

What is the expected output? What do you see instead?
doesn't activate because normalize_uri is defined already by the
wp-diso-profile plugin

What version of the product are you using? On what operating system?


Please provide any additional information below.
assuming it needs the if( !function_exists( 'normalize_uri' ) ) logic that
exists in wp-diso-profile
