Absolutely brilliant…thanks for this thread.
I have been chasing my tail all day on this one and it wasn’t until I read this that I remembered I originally edited my index.php in M$ Expression. What a revelation!
Once I had ftp’d the default index.php over my M$ corrupted version, I stepped into the wp-admin editor, pasted my own content code and voila…now IE looks like Firefox…no more left alignment…happily centred now.
Cannot thank you enough andyfarmerboy for sharing your pain with us.
