Hey E.,
first of all, thank you for the purchase!
Have you defined which sidebars are available for substitution by the custom sidebars, as I’ve recommended in the previous message in this thread? For this, please go to the “Appearance -> Custom Sidebars” admin section, select the sidebars available for substitution in the “Replaceable Sidebars” box, and press “Save changes” to preserve the settings. Please let me know if this solves the issue.
Sincerely,
Andrii / Satori Studio
