# Warning: in_array() expects parameter 2 to be array, null given in…

 * Hi,
 * I am seeing a banner with the same warning for an error on line 117 in the file
   wp-content/plugins/speed-booster-pack/includes/sbp-helpers.php. (see attached
   screenshot 1)
 * [Screenshot 1](https://imgur.com/umTUV6s)
 * The # of warnings (exactly the same text) seems to increase in number when certain
   settings are enabled in the Speed Booster Pack plugin. When reset to defaults
   the warning appears 3 times but increases depending on settings.
 * I went over the relevant code in the Github repository (line 117 in the wp-plugin
   file) and the code is identical. However, when I ran a difference checker some
   code present on Github seems to be missing from the wp plugin file. [(See Here)](https://www.diffchecker.com/yrMnRdcL)
 * I would highly appreciate any help you can provide regarding this issue.

 * Update – I was using the wrong version of the file in the Git repository. Please
   disregard the portion about relevant code. There are no differences in the code
   for 4.1.1 in GitHub or the one in my plugins folder, but the issue of the warning
   banner persists.

 * Hey [@shamajay](https://wordpress.org/support/users/shamajay/),
 * We just released v4.1.3, can you confirm that you’re not getting these warnings
   anymore?
