Hoping someone can help.  When I'm browsing in thrift stores and used book stores, I've always used my tbr list to make sure I don't already have the book.  Lately, however, I can rarely do that because I get an error message that says a secure connection can't be established.  I've tried with wifi turned on and with it turned off; doesn't seem to make a difference.  I recently wasted a whole bunch of credits at a ubs buying books I already have.  (Yes, I know.  This means my tbr list is WAY too long.)  Anybody have any idea what's causing this or what I can do about it?  

For the past few weeks I couldn't access any of the three sites at all because Safari couldn't make a secure connection with PBS. I contacted the site admin and they told me that they had made security upgrades that were probably causing my version of safari to be incompatible. They suggested a number of things to try and I ended up switching from safari to Firefox and now have no problems.

With my tablet I have to use Google plus and type in the WWW.paperback etc. to log in
