@irishartisans – where did you remove the mod_rewrite.c directives / add the rewrite.script directives? Wasn’t that in your .htaccess file?

Most web hosting will allow you access to your .htaccess file. Which hosting company are you using?

Unfortunately, I don’t know anything about rewrite.script so can’t help further on that.

Do the steps I suggested though, and check whether your basic WP installation is working properly first.
