Safari doesn't open some pages
Hi! I've noticed recently that Safari won't open webs like instagram..when I try to log in it lets me write my username and password but when it's going to load the content of the page it remains white.
And I've also noticed that it doesn't open videos on twitter for example, like vines or youtube videos that should be seen directly from the twitter page...What is the matter?
I've tried to restore Safari and make sure there were no updates needed but it has not solved the problem (and I have the latest Safari update)
I would aprecciate the help. Thank you!
