Help - can't access my kid's school website. 403 error
Hi
I need some help. I can surf the web fine but when i get to the school website it just throws up a 403 error. I have checked with the school and they have confirmed that there is no issue at their end as far as they are aware. I have been able to access this site for teh last few years and no-one else seems to have the same issue with the website.
I assume that there is a problem with my computer or my router / ISP but I do not know what? I have tried turning off the computer and then restarting. This did not work.
I have also tried using an ipad through the same router and it comes up with the same error message.
HELP
iMac (27-inch Mid 2011)
