Your plugin is great but I am getting dynamic elements appearing in footer widgets.
For example, I have a membership plugin with a custom login page. When viewing that page it also repeats the login form below each of the footer widget content blocks.
I am also having this issue with another plugin, a course plugin which does the same thing with the dynamic content it is generating on the page.
The site is in a test area on my server but I can setup a public test site if you need to see what I mean.
