Additional –
Even bracketing the script with <!– –> to disable it does not bring the sidebars back. It does keep he posts from displaying but still interferes with the sidebars coming back. I find that really weird because I thought those brackets make the code “invisible” to the server. I have to completely delete the code to get the page to display the sidebars again.
If there is no content posted on the page itself then the code works fine and sidebars appear.
