I would like to use my Pocket Computer or PDA to access LON-CAPA
While we can make no guarantees that LON-CAPA will work with your particular
Pocket Computer or PDA, it runs fine on Apple iPhones, iPads, and iPods using Safari, as well as on several Android devices.
I get "Username and/or password could not be authenticated"
-
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.
-
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.
I get a list of computers ...
This means that the server you attempted to login to is currently not
available. For example, it might be undergoing maintenance. Please click on
any of the other server, giving preference to the ones that say "preferred."
I get "Information needed to verify your login information is missing, inaccessible or expired"
LON-CAPA does internal encryption of password information submitted from the
login screen, but only keeps the decryption information for a day. Simply pull
up the login screen again.
If that does not solve the problem, 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 submit a help request to LON-CAPA support.
The server administrator will be able to verify your situation and re-enable logins.
I hit "Log In," but nothing happens, or I get error messages and
warnings
- The most common problem is that your browser is not one of the browsers
listed above.
- You might have modified the preferences in your browser. In particular, the
following preferences can be a problem:
- Scripting languages, in particular JavaScript, is disabled.
Test: as you click here,
a small window should appear. If no window appears, scripting is disabled.
- 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.
- If all else fails, please try from another computer.
After logging in, I get the message "Welcome," but then nothing happens
- The most common problem is that your browser is not one of the browsers
