Warning: array_key_exists() posted after installation

  • I recently migrated my WordPress Blog to a new host. At the new host I started over with a fresh installation of WP and I then migrated my database over ( I left behind limitattemptbooster tables ).

    After installing a fresh copy of the limit attempts booster plugin into the fresh copy of WP I got these PHP warnings at the top of my dashboard and when trying to go to “settings” for that plugin:

    Warning: array_key_exists() expects parameter 2 to be array, null given in /home3/beforewisdom/public_html/wp-content/plugins/limit-attempts-booster/limit-attempts-booster.php on line 1060

    Warning: Cannot modify header information – headers already sent by (output started at /home3/beforewisdom/public_html/wp-content/plugins/limit-attempts-booster/limit-attempts-booster.php:1060) in /home3/beforewisdom/public_html/wp-admin/includes/misc.php on line 1114

    Warning: Cannot modify header information – headers already sent by (output started at /home3/beforewisdom/public_html/wp-content/plugins/limit-attempts-booster/limit-attempts-booster.php:1060) in /home3/beforewisdom/public_html/wp-includes/pluggable.php on line 1216

    I’m not a PHP or a WordPress developer so any help in resolving these warnings would be appreciated.

    I have temporarily removed the plugin.

    Thank you.
