I can enter my nickname and password, but instead of accepting them the site just re-loads the
login page. I could
login using the same device previously, this issue only surfaced in the past week or so. I tried deleting the history and casche of my phone's browser, but that didn't solve the problem.
Also, I notice on the mobile site that line breaks (such as the one I created in this post to separate paragraphs) are removed from posts.
