Hey JM,
regarding the last issue you mention: this is not an error but was done deliberately, since the Theme Options panel contains some sensitive settings which can significantly affect the entire website – I did not intend such settings to be available to users who are only editors and not the owners/administrators of the website. However, I’ve prepared a custom file for you which you can use to show the Theme Options panel to editors as well: please download this archive from my vault, unzip it, and upload the contained file into the following folder: /wp-content/themes/Ikebana/includes/option-tree/classes/.
Please let me know if the custom file is working!
Sincerely,
Andrew / Satori Studio
