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 support forum – https://wordpress.org/support/topic/conflict-between-this-plugin-and-the-simple-images-sizes-plugin?replies=1#post-7004677
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…
Hi,
I close the issue here because you have opened it on github 🙂
And thanks very much for your quick response to this…
