Alternate Browsers
Many times, the problems students have are the result of an improperly configured Browser. The easiest way to fix this type of problem is to use a different browser.
If you are using Internet Explorer try using Netscape.
If you are using Netscape, try using Internet Explorer.
If you only have one browser on your machine (Usually Internet Explorer) you will have to download and install a new browser on your computer.
Note: Some versions of Internet Explorer and Netscape 7.1 come with a pop-up stopper automatically installed and turned on. See information on Pop-up Blockers below.

Java Settings
Make sure you have Java installed and enabled on your computer. You can download and install it from the Sun web site.
Firefox doesn't automatically pull in the java plug-in. You need to have it installed through Firefox. Even though Enable Java is checked, it probably isn't installed in Firefox.You can get it (an easy Firefox XPI install) here:

Internet Explorer: "Page Can Not Be Displayed" Error
Microsoft Internet Explorer may return a "Page Can Not Be Displayed" error page if the correct SSL settings are not selected. If SSL 3.0 is not checked under IE advanced options, the login page will not load.

Other ISP Browser Errors
If you use AOL, MSN, EarthLink or any other ISP that provides you with a browser other than Internet Explorer, use Internet Explorer for your browser. Many ISPs include a browser that is customized by the ISP. If you are experiencing any problems with St John’s Central, you should try using a non-branded browser. You can use a non-branded browser by minimizing your ISPs branded browser (click the "-" icon in upper right-hand corner) and opening another stand-alone browser such as Microsoft Internet Explorer, Netscape or Mozilla Firefox.
• You can not log in, but instead receive an error page listing a "Password Reset Utility - Exception Report."
• After logging in to St John’s Central, you immediately receive a message stating, "Session has expired."
These errors appear to be related to certain Internet Service Providers (ISPs). Some dial-up companies like Juno and Netzero make use of caching servers that store a copy of Web sites subscribers are trying to view. This way, when a subscriber is trying to view a site repeatedly it will load faster. This works well for many sites static pages but not for sites with personalized dynamic content.

Juno Customers
Please be sure you have the latest version installed. Installing the latest version may resolve many of the problems encountered. If you still experience difficulty, disable your ISPs caching. This accelerator feature which some Juno accounts include is referred to as SpeedBand. This should be disabled when logging into St John’s Central.

NetZero Customers
Please be sure you have the latest version of NetZero installed. Installing the latest version may resolve many of the problems encountered. If you still experience difficulty, disable your ISPs caching. This accelerator feature which some NetZero accounts include is referred to as HiSpeed. This should be disabled when logging into St John’s Central.

AOL Customers
If you are an AOL member, the AOL provided browser has been modified specifically for the AOL web site and does not always support other tasks well. You need to download and install a "full" version of Internet Explorer (or Netscape -- see below for a link).
• Sign into AOL as you normally do.
• Minimize the AOL provided browser.
• Start up the full version of Internet Explorer.
• Connect to your course material.

Note For Mac Users
If you have a Mac computer, other Mac owners have reported that if you are having problems accessing either St John’s Central or WebCT using Internet Explorer, that Netscape has allowed a successful connection, especially if you have OS 9 instead of OS X. Go out to and download and install the version of Netscape that works with your operating system. For more information on Mac OS 9, check the Apple Mac OS 9 Support Page.

Internet Explorer 5.0 Issue
You cannot log into the system at all if you are using IE 5.0 Service Pack 1. If you click the Continue button after reading the warning that you are using an unsupported browser, you will receive a "Page cannot be found" error. This is due to the unsupported encryption algorithms included in IE 5.0 SP1. Although Internet Explorer 5.0 is not a supported browser, you can log in to the system with IE 5.0 if you are using Service Pack 2. However, once logged in, you may still experience usability issues. We recommend that if you are using IE 5.0 on a Windows platform, you upgrade to version 6.0 for best performance.

Netscape JRE Issue
In order to use the Chat application provided by the Luminis system, your Internet browser must be able to access and run a Java Virtual Machine (JVM). In some cases a JVM is provided by your operating system. In other cases, the browser adds a JVM to your computer when it is installed. With Netscape browsers, the JVM is included during installation as part of the Java Runtime Environment (JRE). However, in some installations of Netscape, the JRE is an optional installation choice. If your Netscape browser does not have a JRE installed or enabled, you will see a warning message when you first access the Luminis system. If you click continue, you should be able to use all system functionality with the exception of Chat. The first time you try to use Chat without a JVM, you will be prompted to install a plugin. If you accept the plugin, a JVM will be installed and configured for your Netscape browser and you will no longer see the warning message when you try to access the Luminis system.

Spyware Information Sites

General Information
With the broadband connections becoming common place on the web, the issue of spyware has become widespread. Some websites install files on your computer without your knowledge, typically to collect information about your browsing habits or display advertisements when you are attempting to use the internet. If you find that you get redirected to a third-party site, it is likely that a piece of spyware/adware is hidden on your computer. File sharing(peer-to-peer) software commonly used to share music, software and movie files can also cause problems by placing spyware/adware on your computer.(KaZaA automatically places PerfectNav on your computer which could very well cause a conflict with WebCT. To remove this parasite you must remove KaZaA).

To remedy the problem, it is recommended that you use a spyware removal utility such as the following:

Spyware Removal Tools
Ad-aware - Popular free spyware removal software program
Spybot - Another popular free spyware removal software program
Microsoft Antispyware – New software program

General Information
Popup blocking software is getting more and more popular these days. Many websites use popups to make money. These popups are quite annoying, so many people install programs that will block popups from opening. This seems like a great idea, but these programs often block useful JavaScript too.
If you have installed a pop-up blocker to prevent pop-up advertisements appearing when you use the internet, this may cause problems with many of the features of St John’s Central and WebCT. In particular you may experience problems when new windows are opened within St John’s Central your pop-up blocker may incorrectly identify this as an advertising pop-up and prevent the new window from opening. For example in email when you click on "Compose" or "Reply" the first thing that happens is, a pop-up is created and a new window for "reply" or "compose" is opened. If you have a pop-up blocker enabled it prevents the pop-up window from displaying and making it possible to reply or compose email. Pop-up blockers can be configured to accept pop-ups from certain addresses. Pop-up blocker functions are now included in many anti-virus, internet security, personal firewall, browser, and search & toolbar programs. You need to disable pop-up blocking for the domain.

Known Browsers with Pop-up Blockers.
Internet Explorer 6.0, with Windows XP service pack 2
AOL 8.0 and later

A Note for Mac Users
