Problem - any one or more of the following:

• Users cannot see new content, even after they have just posted it.
  
• Users do not appear to be able to log in.
  
• Some users report that the light bulbs are not working correctly.

Cause:

This is most likely caused by the Web Browser drawing pages from either a local disk cache or a cache at the ISP or Firewall level. Windows XP users could also be experiencing trouble with the default "Personal Firewall" sofware. Other such similar "Personal Firewall" software (Zone Alarm Pro for example) could cause similar problems.

Resolution (look for your browser for specific instructions):

Internet Explorer through Version 5 Series:

1. Select Tools -> Internet Options -> Temporary Internet Files section
   
2. Click "Settings" and enable the option "Every visit to the page". NOTE: Now is a good time to limit the number of megabytes that Internet Explorer has to store pages on your hard disk; its default is 1% of your total hard disk size. Consider reducing that down to 10 Megabytes at this time.
   
3. Click "OK"
   
4. Click "Delete Files"
   
5. Click "OK"

Internet Explorer Version 6 Series

• Tools -> Internet Options Privacy Tab
  
• Click "Advanced"
  
• Ensure settings are the following:
  
  -> "Override automatic cookie handling" - CHECKED
  -> First party Cookies: ACCEPT - selected
  -> Third-party Cookies: BLOCK - selected
  -> "Always allow session cookies" - user discretion

This allows the UBB.classic™ software to work as designed while still blocking potentially malicious third-party cookies.

In addition, the UBB.classic™ software cannot exist within a frameset. Internet Explorer often sees the UBB.classic™ within the frameset as a "third party" and will block the cookies.

Netscape:

• Select Edit -> Preferences -> Click the '+' next to "Advanced"
  
• Select "Cache"
  
• Menu on the right says "Document in cache is compared to Document on network:"
  ->"Once Per session"
  ->"Every time"
  ->"Never"
  
• Choose "Every Time"
  
• Click "OK"

Windows XP users with "Norton Personal Firewall" software, or similar (adding a trusted site):

1. Open NIS.
   
2. Click Options.
   
3. Click Internet Security (or Personal Firewall).
   
4. Click Advanced Options.
   
5. Click the Web tab.
   
6. Click Add Site. A new site/domain box appears.
   
7. Enter the url of the site that you want to receive the referrer information and click OK. That site name appears in the left frame of the Advanced Options window.
   
8. Click the name of the new site.
   
9. Click the Privacy tab.
   
10. Check the "Use these rules for..." box.
    
11. Change the Referrer from "Block" to "Allow."
    
12. Click Apply, and then click OK.
    
13. Click OK to close the Options window.

Thanks to Lisa_P at Threadsdev for these!

If you wish to disable all filtering: Click on custom settings and make sure enable privacy is checked. Then click on the Custom Level tab. Under Confidential settings select medium. Under Cookie Blocking select None:Allow Cookies. Do not place a check mark next to Enable Browser Privacy. Place a check mark next to Enable Secure Connections (https). Click OK and you're all set. Thanks Bob P.!


Additional Information:

Check your local computer's clock. If it is inaccurate, please reset it to your current local time, clear out your browser cache, clear out any cookies set by the site, and try again.

If you are using a cable modem, please contact your cable modem provider to discuss the page cache that they may be running on the system. Be prepared to use an alternate provider (dial up) as a test of the page cache if they are indeed running one. Many hosts with cache systems claim that they are 'transparent' when that is not the case.

Also know that many large ISPs around the country will run cache servers that only clear out at scheduled intervals. This can affect performance regionally and make content fail to show up correctly for your users in these areas where the cache has not cleared for a while.
