I am working on some troubleshooting for a non-profit website someone else designed originally using WordPress, and I've found a bug that shows up in older versions of IE.
The problem is that when you go to a parent category in older versions of IE (never a problem in Chrome or Firefox), the child categories are supposed to display in the sidebar as a bulleted list of links, but instead the background image that is used to display the parent categories as sidebar "buttons" just repeats itself for each child link. The links have the right URL, but the display is wrong.
I'm not sure whether this is an issue with the CSS or the PHP, so I don't know exactly what code would be useful, but has anyone had a similar problem?
This is an example of a page that has the problem.
Here's the section of the stylesheet that sets up the category list:
[CSS moderated as per the Forum Rules.]
Here's the sidebar.php file:
Happy to provide anything else that's necessary!
