Editing Help:Logging in (section)

=== Login issues and problems ===
If you find yourself unable to log in, you may have one of the problems addressed in the following paragraphs. If none of them seem to apply, ask for help at the [[Wikipedia:Help desk|help desk]].

; The login link is obscured
: If you cannot click on the login link, for instance because it is obscured by other text, use this [[Special:UserLogin|direct link]] to the login page. It may be helpful to add the page to your browser's bookmarks/favourites.  (This problem may occur on certain browsers when using a large minimum font size.)
; My username and password are refused
: Both usernames and passwords are [[case-sensitive]] on Wikipedia. Did you remember to type in the right capitalization? For example, if you registered under MyUserName, you will not be able to log in as Myusername (notice the subtle difference in spelling). The same goes for your password. The only exception is the first character of the username, which is capital by default.
; I get logged out just after logging in
: There are a few possible causes of this problem:
:* If you appear to have logged in, but as soon as you try to look at a page after 'Log in successful', you appear logged out again, it is very likely to be a [[HTTP cookie|cookie]] problem. See [http://www.google.com/support/accounts/bin/answer.py?&answer=61416 this brief tutorial] on how to enable cookies for your browser.
:* Make sure your computer's date and time are set correctly; if they are not, cookies may expire before they are supposed to. Note that some [[Firewall (computing)|firewall]] and [[Ad filtering|ad-blocking]] software may interfere with the cookie that Wikipedia uses to keep a person logged in.
:* Some ISPs use [[transparent proxy|transparent proxies]] which cause problems logging in. This happens most often with some satellite ISPs (particularly [[HughesNet]]/[[DirecWay]]/[[DirecPC]]).
:* Occasionally, a user may find themself "automatically" logged out between beginning an edit and saving it, or when switching between multiple wiki pages open in multiple windows or tabs. This can be a result of your browser's cookie, cache, or firewall settings, but sometimes, especially during heavy server load, the system can "glitch" and your login information will be lost, resulting in a logout.
; Other causes
: If you are absolutely sure that the login information you have entered is correct, then someone else may have compromised your account. In this case, your account may not be recoverable unless you can prove that the account is yours. In rare cases, your account may have been renamed or [[Wikipedia:Changing username/Usurpations|usurped]], especially if it has few or no edits. You can see if your account has been renamed by viewing the [[Special:Log/renameuser|user rename log]] and search for your username in the "Title" field.
; I get a message that my IP address has been autoblocked
: Follow the instructions listed on screen on how to request an unblock or send an email to the {{mono|unblock-en-i}} mailing list.
