Enable Pop-Ups for Canvas
While using Canvas, if you are unable to view discussion postings, quiz windows, or download links, then you need to disable pop-ups. Depending on the pop-up blocking software you are using, you may be able to set the Rio Hondo College Canvas site (http://riohondo.instructure.com) as an allowed site, or you may need to turn-off the pop-up blocker while using Canvas.
Pop-up blockers work in the background while you browse the internet. When they detect a pop-up window that may be an unwanted advertisement, they automatically close the window. This can prevent Canvas from performing properly.
To disable pop-up blockers for Canvas:
a) Search your hard drive for any software with “pop-up” in the name. Disable it or set the Rio Hondo College Canvas site (http://riohondo.instructure.com) as an allowed site.
b) Pop-up blocking functions are included in some anti-virus, internet security, personal firewall, and browser programs. Disable the relevant setting in the program or set the Rio Hondo College Canvas site (http://riohondo.instructure.com) as an allowed site. Examples of programs that include pop-up blocking functions include the following.
