Problem with displaying Smarty template in Internet explorer

I have converted my existing website to Smarty template (my very first project with 1 day of smarty experience under the belt)

Prior to conversion my website looked fine in IE and FF.

After the conversio开发者_Go百科n FF still looks okay however in IE everything falls apart. I have tried comparing the source code in IE and FF and everything looks exactly the same. Any help is appreciated.

Since Smarty is just the templating system that generates the HTML sent to the browser, the issue probably occurred when you split up your existing site into parts. Unfortunately it isn't very easy to find out what is wrong with a full project on SO. That said, here are some tips on debugging the issue.

Load your old site and copy the source from the browser (doesn't matter which browser as the server sends the same HTML*). Load your new site and copy the source from the browser. Diff the two sources to find the differences.

I think that's the best place to start. If the new site is sending the exact same HTML to the browser, then it would seem that some resource isn't being loaded (bad link) or javascript isn't being executed in IE, which should be separate from Smarty. For that check IE's Developer Tools and make sure no CSS is getting a 404 and no js exceptions are being thrown.

*As long as you aren't modifying things on the server based off the User-Agent sent, which is not common.
