My website doesn’t load on Explorer

It loads on IE8 on Vista, with one error. Sadly the error message is truly useless.

File not found: https://www.bbdialog.com/wp-content/themes/thesis_151/custom/custom.css?071609-90739: Not Found

According to https://www.xhtml-css.com/check# that custom file is not found. Mabe that’s what’s blocking my IE7 . After showing your site it indeed pops up with an error and quits after giving OK.

Yep. henkholland is right. It is loading a 404 page for custom.css. I’ve never seen a bad CSS file crash a page though. And like I said, it loads in IE8.

thanks for your messages henkholland and apljdi. Any ideas on how i should move forward and get it working?

“Operation Aborted” is an IE bug triggered by certain types of javascript in a plugin, theme, widget, addon, or code that you yourself added.

Well, how about first checking the theme’s directory on the server for the “MISSING FILE”? Apparently your theme has a custom.css in themes/thesis_151/custom/custom.css? That’s the file where it stores some settings, leaving the main style.css unchanged for easier future theme updates.
It should be there from the upload or it was (was not) created upon them installation? Check the site of the theme itself.
