<h1>Login Problems with LON-CAPA</h1>
<h2>Which browsers can I use with LON-CAPA?</h2>
LON-CAPA is designed to work with the following browsers
<ul>
<li>Mozilla version 1.0 and higher</li>
<li>Netscape version 4.7 and higher</li>
<li>Internet Explorer version 5.0 and higher</li>
</ul>
on the following operating systems
<ul>
<li>Linux</li>
<li>UNIX</li>
<li>MacOS</li>
<li>Windows</li>
</ul>
If you have problems logging in with any browser or any operating system not
listed above, please <b>use another browser or computer.</b>
<h2>I get "Username and/or password could not be authenticated"</h2>
<ul>
<li>
The most common problem here is that the Caps-Lock button is pressed. Usernames
and passwords are case sensitive, so it does matter if something is typed with
lowercase or with uppercase letters.
</li><li>
The second most common problems is that users accidentally go to the wrong 
server. LON-CAPA is running at many universities, colleges, and schools.
Especially if you hit upon this page by looking for "LON-CAPA" in Google or
some other search engine, you might have hit a server at another place. Please
make sure to use the URL provided to you. 
</li></ul>
<h2>I get "Login token missing, inaccessible or expired"</h2>
This is a very rare problem. If it occurs, please wait for 20 minutes, reload 
the login page, and try again. If after 20 minutes LON-CAPA still gives you 
the same message, please email the Server Administrator listed on the login 
page. The Server Administrator can verify your situation and re-enable logins.
<h2>After logging in, I get the message "Welcome," but then nothing happens
</h2>
<ul>
<li>The most common problem is that your browser is not one of the browsers
listed above.</li>
<li>If you have a supported browser, it might be hung. Please completely quit
your browser, and start it again.</li>
<li>You might have installed a filter against so-called "pop-up ads" (those
obnoxious windows that come up into your face trying to sell you something
while you are surfing). These filters will prevent LON-CAPA from running
properly. Please disable the filter for your school's domain, for example
"xyzu.edu."</li>
<li>You might be getting your internet access from a free service provider 
which adds banner ads to your pages. These ads conflict with LON-CAPA, you 
will need to use another provider.</li>
<li>If all else fails, please <b>try from another computer.</b></li>
</ul>
<h2>I hit "Log In," but nothing happens, or I get error messages and 
warnings</h2>
<ul>
<li>The most common problem is that your browser is not one of the browsers
listed above.</li>
<li>You might have modified the preferences in your browser. In particular, the
following preferences can be a problem:
<ul>
<li>Scripting languages, in particular JavaScript, is disabled.</li>
<li>The security settings are cranked up to a higher level. In particular, this
might prevent unencrypted submission of passwords (LON-CAPA actually does its
own encryption), or cross-server submission of forms.
</ul></li>
<li>If all else fails, please <b>try from another computer.</b></li>
</ul>
