I've got a Zen Cart site running at http://kaysshoes.com/ which has suddenly become unreachable via Internet Explorer on Windows.
The site works find on Firefox 2.0 (Mac and Win), Safari 2.0 (Mac), Internet Explorer 5.2 (Mac) and Opera 9 (Mac).
Does not work in Internet Explorer for Windows, versons 7.0, 6.0, or 5.5.
IE7 gives the following non-helpful error message:
"Internet Explorer cannot display the webpage
Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address."
Since Firefox can reach the site from the same machine, and the address is typed correctly, none of these explanations holds water.
6.0 and 5.5 give no error message, they just load a blank page.
A simple HTML page (no PHP) works fine on IE: http://kaysshoes.com/index_old.html
But the site worked fine as is on IE until today or last night--last site update was yesterday at 8:30 a.m., and the site worked fine at that point. This was a simple HTML tweak, which I've since reversed with no effect.
I'm going to start a file-by-file comparison of this site with a copy of the site from last week, but any hints would be most welcome.
The site is simultaneously afflicted with a login problem in the browsers it does load into. There's more here:
I've got no idea if these two problems are related.
Has anyone encountered simliar problems? Any clues about what's happening here? Thanks.
