Answer 1

Read the error message

Declaration of JsHelper::link() should be compatible with AppHelper::link($title, $url = NULL, $options = Array, $confirmMessage = false) [CORE\\Cake\\View\\Helper\\JsHelper.php, line 434]

Then look at the method signature for that method in the core :

// JsHelper
link($title, $url = null, $options = array())

Then look at the method signature in the warning:

//AppHelper
link($title, $url = NULL, $options = Array, $confirmMessage = false)

Then read the warning again, it's saying they don't match.

Solution

Change the AppHelper, a class in your application, to have the same method signature:

//AppHelper
link($title, $url = NULL, $options = Array)

And adjust any logic it contains accordingly.
