Hi all and thanks for taking the time to read... Bear with me, while I try to give full information (and hope I'm putting the q in the right forum)...
Since yesterday afternoon, I've been unable to access 3 sites which I generally access on a daily basis. I know that all 3 sites are functioning perfectly normally for other users.
2 are forums and 1 is Etsy. So no major Flash or Java script stuff.
I've tried both Firefox (my regular browser) and Safari. I seem to recall recently updating to the latest Firefox, but don't recall when/what the last Safari update was.
I'm on an iMac and have to confess I'm clueless as to what OS I'm on
I connect to the internet via the airport and a Belkin ADSL wireless router.
So far, I've tried rebooting everything, clearing the cache & cookies, disabling the router's firewall, and switching it all off for a couple of hours while I went off for some shuteye.
On the router's Utility page, I've noticed there's a change to the DNS servers. I'm with Nildram, which was taken over by Tiscali and the primary & secondary servers have been changed to Tiscali servers... When this happened is anybody's guess... I've only opened the utility site this week because of my problems! lol
I don't seem to have any problems with accessing other sites e.g. mr site, my own website (thankfully!) yahoo, hotmail, facebook, ebay, wikipedia and the BBC. Some of which I access daily, others of which I just tested out today to make sure the system was working OK.
Other than the router's default firewall (now disabled) I don't have any other security systems installed that might be denying me access to these sites for whatever reason.
I confess that I'm a bit of a technoklutz when it comes to computers in general and Macs in particular, as I panic cos I assume I'll get it all wrong if I try to tackle anything too tricky, which I might have been brave enough to do with a Windows pc!
So nice, simple answers aimed at the technically-challenged would be really appreciated *flutters eyelashes and flicks blonde hair out of eyes*
Is there anything else I could try to regain access to these sites?
I'm too late to call my ISP tech support tonight, but I'll try them tomorrow if I can't sort it myself (with a little help from anyone willing to give it!)
