not very computer savvy. My husband has been trying to fix it. He did flush the DNS cache and we've cleared files, cookies, history, etc., etc. Like I said, I'm now able to get on........but we don't know why. We have an AT&T Aircard modem. We plug it into our computer, and that's how we get internet access. We did an upgrade to it a couple months ago, and that's when all the trouble started. My husband could access the site at work, on all his computers and his laptop too. But at home, if he used the Aircard modem on his laptop, he could no longer access the site. So we deduced it had something to do with the Aircard upgrade. He talked to several techs at AT&T and Sierra Wireless and they couldn't figure out what was going on. I also could no longer access my Photobucket account. But today, out of the blue, I'm able to log on to Gardenweb AND access my Photobucket account. We haven't done anything different to the computer recently. My husband thought it had something to do with Gardenweb's security certificate. And the fact that garden web had just the http and not the https. I'm sorry if I'm not making sense, because of my not be very computer savvy. But........I'm finally able to access Gardenweb and for that I am grateful. I just hope it doesn't happen again! I will print out everything you've suggested in case it does happen again.
