I attempted to add some simple javascript to the status_interfaces.php page to implement a dynamic timer/counter for PPP link uptime. I failed because I believe that this page for some reason has stopped executing javascript. I took a dead simple code snippet and pasted it into the right place in the /usr/local/www/javascript/status_interfaces folder and it won't execute. I verified that the script text is actually showing up in the page source code in the browser.. 
I browsed through the source as displayed by my browser and there is a LOT of javascript in the header for this page. Its too complicated for me to even know if its all necessary. Is it all necessary? Is there a chance that some script function is blocking execution of additional scripts?
