after changing my site to display pretty URLs last week (via gen_htaccess), all has been ok till today when i gave someone a link to my blog, of which they replied saying they got a 'page not found' message, so i deliberately entered a bogus URL after my site link expecting my custom 404 error page to pop up, but rather than displaying error.php, the server searched for /error/?=404, no error page there.
and once or twice i recall this URL being displayed in my browser http://simmonsstudio.tk/home/u959751435/public_html
