Some of the vendor links you are attempting to add recently contain no actual link (which means they are being removed when discovered. Please make sure to check them.
If you are having trouble with the new VisualEditor that wikia made a default, here is how to change back to the old way of seeing edits:
Place your mouse or cursor over your user name in the upper right hand corner of the any pages(in the dark green area on the very top). You shiould see a drop-down menu including "My preferences". *Select "MyPreferences" *On that page, select the "Editing" tab *In the section "Editing Experience", select "Wikia's classic rich-text editor" *Make sure to click the tiny "Save" button at the bottom, and you should be all set.
Okay, thanks! I just want to clarify that I can remove other people's links to sold patterns. In the past, I removed a sold link and got in trouble for it! What about links for patterns that go to the front page of someone's site and not the actual pattern?
The same goes for those. One some sites, when a pattern is no longer available, it redirects to the front page (e.g. MOMsPatterns, Out of the Ashes, etc.). Be aware thought that some sellers list patterns for a whole decade or theme on one page - those are valid.
