Question

Getting an error with Dev Demon updater:

Message: Non-static method Updater_helper::arrayExtend() should not be called statically, assuming $this from incompatible context

REF #TT

Answer 1

This is known error of Upgraded PHP version.

As you know a static method should ideally defined as static function(){} where static means the method can be called without an instance of the class.

For current scenario, Follow the staps:

1. Open FTP and go to system > expressionengine > third_party > updater > libraries folder.
2. Open file named updater_helper.php

3. Search function function arrayExtend( and change it from

   public function arrayExtend($a, $b) {
   

   TO

   public static function arrayExtend($a, $b) {
   

arrayExtend is not a single function that is static and defined normally. There is more functions in same file

getThirdPartyPath()

getThemePath()

getThirdPartyThemePath()

arrayExtend($a, $b)

You need to change all this functions to static by adding public static function fun_name()
