 * I can’t say for sure this just appeared with this last update, but I did just
   notice it…
 * This error is appearing on the _Media_ settings page between _“Select which post
   type source thumbnails you want to rebuild:”_ and the area/section where the 
   selections are made –
 * _Warning: array\_key\_exists() expects parameter 2 to be array, null given in/
   home/purelialch/public\_html/wp-content/plugins/simple-image-sizes/templates/
   options-media.php on line 88_
 * I’m not going to be comfortable using Simple Images Sizes until I know this is
   not going to create other problems…?
 * Kind regards…

 * I have another site with same theme and mostly same plugins and with the 3.05
   version still installed, and the error warning is not appearing, which I believe
   suggests that it is related to 3.06… ?

 * I had some time to explore this on a dev/test site and have discovered that it
   is something going on specifically between _ Simple Image Sizes_ and the _WP 
   Simple PayPal Shopping Cart_ plugin… No other plugins I have deactivated have
   had any effect…
 * When I deactivate _WP Simple PayPal Shopping Cart_ the error goes away, when 
   reactivate it the warning reappears…
 * Also, when I reinstalled 3.05 the warning was still there, so it is not after
   all related specifically to 3.06… I set various image sizes a good while back
   and this is the first time since then that I have been in there to see the warning,
   so no telling when it appeared… The 3.06 update simply reminded me to go in and
   look…
 * The shopping cart is necessary, and your _Simple Image Sizes_ plugin is very 
   helpful as well…
 * I will copy this over into a topic in in the _WP Simple PayPal Shopping Cart_
   plugin support forum and see what happens…
 * Kind regards…
 * P.S… Here is the support topic in the _WP Simple PayPal Shopping Cart_ plugin

 * I have further narrowed it down, on a recent WP install with 2015 as the theme
   and only _WP Simple PayPal Shopping Cart_ and _Simple Image Sizes_ activated,
   no other plugins activated, the warning/error as reported is there…
