1.1 www 20: <h2>Which browsers can I use with LON-CAPA?</h2>
21: LON-CAPA is designed to work with the following browsers
22: <ul>
23: <li>Mozilla version 1.0 and higher</li>
1.9 albertel 24: <li>Mozilla Firefox</li>
1.7 www 25: <li>Camino</li>
1.1 www 26: <li>Netscape version 4.7 and higher</li>
1.7 www 27: <li>Safari version 1.1.1 and higher</li>
1.4 www 28: <li>Galeon version 1.2 and higher</li>
1.13 www 29: <li>Google Chrome</li>
1.17 raeburn 30: <li>Microsoft Edge</li>
1.16 raeburn 31: <li>Opera version 10 and higher</li>
1.13 www 32: <li>Internet Explorer version 5.1 and higher</li>
1.1 www 33: </ul>
34: on the following operating systems
35: <ul>
36: <li>Linux</li>
37: <li>UNIX</li>
38: <li>MacOS</li>
1.13 www 39: <li>Microsoft Windows 98 and higher</li>
1.1 www 40: </ul>
41: If you have problems logging in with any browser or any operating system not
42: listed above, please <b>use another browser or computer.</b>
1.15 raeburn 43: Please please submit a help request to <a href="/adm/helpdesk?origurl=%2fadm%2floginproblems.html">LON-CAPA support</a> if you have any problems.
1.3 www 44: <h2>I would like to use my Pocket Computer or PDA to access LON-CAPA</h2>
45: While we can make no guarantees that LON-CAPA will work with your particular
1.13 www 46: Pocket Computer or PDA, it runs fine on Apple iPhones, iPads, and iPods using Safari, as well as on several Android devices.
1.1 www 47: <h2>I get "Username and/or password could not be authenticated"</h2>
48: <ul>
49: <li>
50: The most common problem here is that the Caps-Lock button is pressed. Usernames
51: and passwords are case sensitive, so it does matter if something is typed with
52: lowercase or with uppercase letters.
53: </li><li>
54: The second most common problems is that users accidentally go to the wrong
55: server. LON-CAPA is running at many universities, colleges, and schools.
56: Especially if you hit upon this page by looking for "LON-CAPA" in Google or
57: some other search engine, you might have hit a server at another place. Please
58: make sure to use the URL provided to you.
59: </li></ul>
1.3 www 60: <h2>I get a list of computers ...</h2>
61: This means that the server you attempted to login to is currently not
62: available. For example, it might be undergoing maintenance. Please click on
63: any of the other server, giving preference to the ones that say "preferred."
1.5 www 64: <h2>I get "Information needed to verify your login information is missing, inaccessible or expired"</h2>
65: LON-CAPA does internal encryption of password information submitted from the
66: login screen, but only keeps the decryption information for a day. Simply pull
67: up the login screen again.
68: If that does not solve the problem, please wait for 20 minutes, reload
1.1 www 69: the login page, and try again. If after 20 minutes LON-CAPA still gives you
1.11 raeburn 70: the same message, please submit a help request to <a href="/adm/helpdesk?origurl=%2fadm%2floginproblems.html">LON-CAPA support</a>.
71: The server administrator will be able to verify your situation and re-enable logins.
1.3 www 72: <h2>I hit "Log In," but nothing happens, or I get error messages and
73: warnings</h2>
74: <ul>
75: <li>The most common problem is that your browser is not one of the browsers
76: listed above.</li>
77: <li>You might have modified the preferences in your browser. In particular, the
78: following preferences can be a problem:
79: <ul>
80: <li>Scripting languages, in particular JavaScript, is disabled.
81: <i>Test: as you <a href="javascript:alert('PASSED TEST');">click here</a>,
82: a small window should appear. If no window appears, scripting is disabled.</i>
83: </li>
84: <li>The security settings are cranked up to a higher level. In particular, this
85: might prevent unencrypted submission of passwords (LON-CAPA actually does its
1.12 raeburn 86: own encryption), or cross-server submission of forms.</li>
1.3 www 87: </ul></li>
88: <li>If all else fails, please <b>try from another computer.</b></li>
89: </ul>
1.1 www 90: <h2>After logging in, I get the message "Welcome," but then nothing happens
91: </h2>
92: <ul>
93: <li>The most common problem is that your browser is not one of the browsers
94: listed above.</li>
1.3 www 95: <li>If you have a supported browser, it might be hung.
96: <b>Please completely quit
97: your browser, and start it again.</b></li>
1.1 www 98: <li>If all else fails, please <b>try from another computer.</b></li>
