I want to update some arc series for Star Wars series. For example, this issue does not have the Arc Serie "Skywalker Strikes" : http://comicvine.gamespot.com/star-wars-5-book-i-part-v-skywalker-strikes/4000-489328/
But when I want to make the change, I get the confirmation message that I'll add a new wiki page for that Arc Serie, and then, when I type a comment and click on "save", I got a red banner at the top of the page saying there was an error. After that, the button is greyed and I just have to reload the page to leave that state.
Can someone help me ?
