The custom color was saved in customizations. I tried to use it on widget bottom 3, class curve mycustom.
As for the error for widgetkit plugin this is the same error code I got when trying to upload the child theme through the dashboard. I don’t have a server space issue.
Besides it has to be downloaded from Yootheme’s website.
I did try to upload it through the /wp-content/plugins/ but it’s not working. There are tons of subfiles and I don’t know which to upload as most of them are allowed.
I uploaded widgetkit.css and php and neither worked. Guess I’ll up load all of them and see what happens.
Let me know when you try the custom color which is #B0d183. IT’s a green color that looks like it blends well with your color scheme. Although I’m color blind some shades of green so I may not see the same color you see. Let me know if you think it blends.
