safari cannot open page because too much redirections

Hi to all,

I have a Mac Book Pro with OsX 10.9.5 and, I guess since last automatic update, I get with the etihad homepage the message "Safari cannot open page because too much redirections". But the same homepage work on my ipad perfect.

Also I have a problem to login on a closed area of a membership homepage which worked before update. As well here I am able to login with my ipad.

I guess, some settings were change, but I have no idea what and where ... ?

Can anyone of you help me or have same problems ?

Thanks a lot for your assistance,

yours Roland
