Can't add blocks using block manager to the right side of the site

[LYM3R]

I am having an issue with putting the WYSIWYG block using block manager to the right and left side of the site. I know this is possible as I can do it using the default theme but can't do it using my current theme.

You would need to contact the author of your custom theme if you are having issues only on that theme. Unfortunately, we are unable to assist you with custom items
