Latest WordPress support

One of the reasons Ron & I both replied is that we are using the plugin ourselves on newer instances of WordPress, including the latest.

We need way more details in order to help.

“But right now, using Executive Pro and Generate Pro, no sidebars are showing.”

Did you create a custom one?

Also – if you are a theme customer, you CAN submit a ticket for our plugins. We get to those tickets before we visit these forums.

I can also verify I installed and activate Simple Sidebars n my site running 4.2.2 and did not get the same errors.
