General Browser Weirdness


If your browser is not behaving normally and giving you blank pages instead of content, or crashing periodically, or your "Add attachment" button isn't working any more, you need to clear your browser cache (the temporary files that your browser uses to keep track of recent pages)

Here's how:
  • Firefox:  Tools, 'Clear Private Data' clear 'Cache' only.
  • Internet Explorer:   Tools, Internet Options.  On the default 'general tab', in the 'browser history' section, choose 'delete.  Choose 'delete' beside the top option -- temporary internet files.
  • Safari 4.0 for Macintosh OS X Open Safari. Click on Safari in the upper toolbar and Select Reset Safari. Click Empty Cache and Remove All Cookies. Click the Reset button.
Then, close your browser and restart.

If you are using Internet Explorer and the problem is not resolved, please consider downloading and installing Firefox from www.firefox.com .  It's fast and free and more compatible with the learningSystem.





Internet Explorer is blocking all of my Word/Powerpoint downloads -- blank screen when I try to open a document

Microsoft Word and Powerpoint documents can contain Macro Viruses, so Internet Explorer is set by default to BLOCK ALL OF THESE DOWNLOADS.  Changing the setting below will allow you to CHOOSE which documents to open (like from sources that you trust).

You will know if Internet Explorer is blocking your downloads if you see a screen like this one when you click on a document in the learningSystem:

[screenshot of information bar]


To tell Internet Explorer to stop blocking file downloads:

Tools, Internet Options, Security, 'Custom Level' -- scroll down to 'Downloads' section (about 1/3 of the way down the window)

First item under 'downloads' is 'Automatic Prompting for file downloads"   -- Set that to 'ENABLE' instead of 'DISABLE'.

Save, and close Internet Explorer.  Open Internet Explorer again and login to the learningSystem.  When you try to open a document this time, you'll be given an "Open", "Save", "Cancel" option box.



An alternative to all of this is to download and install Firefox (www.firefox.com) a better, faster browser that should work right away.




"Session  Already Running" message


If you are already logged in to the learningSystem, and you attempt to login again on another tab in your browser, you will get a 'session already running' message.   You can only login to the learningSystem once per browser.  

If, however, you are not logged in to the learningSystem, and you are getting a 'Session already running' message, then you need to clear your browser cache (the temporary files that your browser uses to keep track of sessions)

Here's how:
  • Firefox:  Tools, 'Clear Private Data' clear 'Cache' only.
  • Internet Explorer:   Tools, Internet Options.  On the default 'general tab', in the 'browser history' section, choose 'delete.  Choose 'delete' beside the top option -- temporary internet files.
  • Safari 4.0 for Macintosh OS X Open Safari. Click on Safari in the upper toolbar and Select Reset Safari. Click Empty Cache and Remove All Cookies. Click the Reset button.
Then, close your browser and restart.




BLANK PAGE when trying to log in to the learningSystem


If you are seeing a BLANK PAGE when you are trying to login to the learningSystem, and at the bottom of the browser window the word "Done" appears, then you need to clear your browser cache (the temporary files that your browser uses to keep track of sessions) so that the myLearningSystem page can display properly.

Here's how:
  • Firefox:  Tools, 'Clear Private Data' clear 'Cache' only.
  • Internet Explorer:   Tools, Internet Options.  On the default 'general tab', in the 'browser history' section, choose 'delete.  Choose 'delete' beside the top option -- temporary internet files.
  • Safari 4.0 for Macintosh OS X Open Safari. Click on Safari in the upper toolbar and Select Reset Safari. Click Empty Cache and Remove All Cookies. Click the Reset button.
Then, close your browser and restart.




I can't open some of the documents that my instructor is posting


Your instructors will be primarily posting three types of documents in the learningSystem:
  • Microsoft Word (.doc)
  • Microsoft Powerpoint (.ppt)
  • Adobe Acrobat/Reader (.pdf)
Please consult the "Plug-in Check" link on the left menu of this page ( http://www.trentu.ca/mls/plugins ), and use the '[test drive]' option beside each of those file formats that is displayed there.  If you cannot open the test drive document, then use the 'download' link to the right of the item to download and install the free viewer/plugin for that software.  Reboot your computer and attempt to open the document(s) again.


LearningSystem Server as "Trusted Site" for Internet Security & Pop-ups

The official name of the LearningSystem server is 'webct.trentu.ca'.   When setting up the server as a 'trusted site' for Internet security purposes, you may need to specify both of the following in the "Tools', 'Internet Options', 'Security', 'Trusted Sites' window:

https://webct.trentu.ca:443      (for actual secured login)
http://webct.trentu.ca        (for general  access)


Firewall Ports Used by the LearningSystem:

The following are the port numbers which must be enabled for the LearningSystem to work at Trent. If you use a personal firewall application, please open these ports so that your web browser can communicate on these port numbers. If you don't have a personal firewall but are still having problems, contact your local Internet Services Provider to ensure that they have enabled these ports on their institutional firewall.

Port Used for
80: Normal web server port
443: myLearningSystem SSL secure server.
Used on login screen to encrypt password transmission.
Also used by "WebDAV" for transferring files to the server.
2048: Library Proxy Server Login
2304: myLearningSystem Chat tool port
8080: Library Proxy Server



I'm Logging in outside of the portal, and boxes to enter  username & password don't appear

If you click on the 'Login to myLearningSystem' hyperlink from www.trentu.ca/mls , and are immediately given an "unauthorized" message, your browser is likely currently set up to try to access any 'Login sites' anonymously.  You need to turn this 'anonymous login' setting off before you'll be allowed to login with your own login information.

Please follow the instructions in the Anonymous Login section of one of these pages depending on the browser that you're using:
