I clicked the preview button today on a post and it sent me to a blank page (About:blank) using chrome browser.

thats what you get for having chrome installed

chrome is the only non-Explorer browser that is 'fully' compatible with the school blackboard even though they claim firefox is it acts up.


the problem appears to have sorted itself out anyway for now

Haha thats funny cuz my school is the exact opposite we are not supposed to use chrome because it supposedly doesnt display certain things properly. They suggest using IE9 or Firefox

This is why web development gets tough. Each browser plays differently with the code now because browser developers of (firefox,chrome,etc...) think everyone should adapt to their way how code gets handled. Web developers now are forced to add additional coding to support each browser & things can get ugly if not properly done.

My school also uses blackboard and they state in bold that IE9 is not recommended as it causes issues.
