Forum:SH Archive/Talk page problems

I'm new to the editing facets of Wookiepedia and I seem to be having a slight problem. When leaving a message in the discussion section of an article, the site keeps informing me that I cannot complete my submission because I am using external links that have been determined as harmful. In all of these cases I didn't type the code for any external links. I even tried just typing one word and submitting it in the Talk section. It still says that it detects external links.
