I have tried Defender on another site and it's pretty unhappy..
Defender installed and seemed to activate fine, but when I go to the Defender tab to set it up, I get a huge number of the following line...
Warning: in_array() expects parameter 2 to be array, boolean given in my-path-to/wp-content/plugins/defender-by-played/admin.php on line 53
After dozens of the above, the regular Defender setup is there.
Also on the live page I get...
Warning: in_array() expects parameter 2 to be array, boolean given in my-path-to/wp-content/plugins/defender-by-played/defender.php on line 48
Any clue as to what's up?
