Q: Cannot connect to bluehost.com

Deselecting Allow plug-ins made no difference. :-(

I did that a few days ago. It made no difference. Thank you for trying, Carolyn.

Thank you, Eric, but I've already tried the suggestions at the first two links and do not want to go into Terminal, which is what your third link suggests.

This problem should not be marked as solved.

I apologize, Carolyn. I wasn't aware of marking the discussion solved, though obviously I must have. I will be more careful in the future.

Since making my original post above, I have discovered other quirky misbehaviors of Safari on this computer. In each case, I am able to use Firefox successfully. Chrome also works. I have been reluctant to upgrade to El Capitan on this computer because of my experience with it on another computer, where my Mail program works improperly since upgrading to El Capitan. So far, at least, I have not had those Mail problems with Mountain Lion on this computer. As long as I can do a work-around using Firefox or Chrome, I am reluctant to upgrade to El Capitan here. I know I can't continue being a Luddite forever, though.

Thank you so much, Eric. These suggestions are exhausting just to read, but I will definitely try them if my work-around stops working. I am happy that they do not require my going into Terminal, which always frightens me. Again, thank you.

Eric, I have a question. When I do eventually upgrade to a newer operating system, is my current problem with Safari likely to follow me?
