i found this solution,
maybe this will help you. good luck
I found a solution in the suggested Mac fixes. I was only having problems viewing content from one site (Weather Network). The solution was to go into Safari Preferences, under Privacy and list all Details. This provided a log of all sites where cookies, etc had been used. I found the Weather Network domain page and cleared all content from it. I was then able to reload the Weather Network page with no issues. I assume this would work for other similar singular sites.
