Unsupported Browser error in Internet Explorer

If you access www.onlinecub.net using Internet Explorer 10 or 11 and are receiving an Unsupported Browser error, it is likely you are in Compatibility View (or mode). If you are in Compatibility View, www.onlinecub.net will detect your browser as Internet Explorer 7, 8 or 9. These browser versions are no longer supported. You can easily turn off Compatibility View by clicking on the icon of the broken piece of paper to the left or right of your address bar (depending on your Internet Explorer version). We also recommend that you remove all www.onlinecub.net related domains from your list of sites for which Compatibility View is enabled. The steps to follow differ slightly per IE version.

1. In Internet Explorer, press the Alt key to display the Menu bar (or right click the Address bar and then select Menu bar).
2. Click on Tools and select Compatibility View settings.
3. Select all www.onlinecub.net related domains under Websites you have added to Compatibility View.
4. Click on Remove.
5. Verify whether the option Display all websites in compatibility view is turned off.
6. Click on Close.
