The "
Internet Explorer cannot open the Internet site http://<Web site>.com. Operation aborted." message is generated from a known IE bug. Microsoft's help page on this is
here including workarounds. It has to do with IE not correctly understanding JavaScript in nested containers/blocks and vB 3.7 users can also be affected:
The thing you need to do is to find the 'offending' JavaScript, and once found, either remove that JavaScript, or turn off the related feature via the ACP, or edit the templates so the JavaScript isn't nested in DIVs, TDs, etcetera too deeply. If you remember this site pre vB 3.7, there was a graphical design on the sides of the forum. That design is now gone, as vB 3.7 contains more JavaScript and this site became affected too. Removing the TABLE/DIVs used to display the graphical design on the sides of the forum made IE happy.
