MacAir issues with 2 sites

After many times of accessing 2 sites, my Mac won't load content on one of them even after I remove blockers and "allowed" on the site. On the other site, it will open content but won't open the images / pictures on the site. I can see everything but the images. Again, I've removed blockers on that site also and "allowed" access. Appreciate the help if you have suggestions.
