Need urgent help

Fatal error: Smarty error: [in index.html line 1]: syntax error: invalid attribute name: 'header.html\' (Smarty_Compiler.class.php, line 1559) in /home/babqatar/public_html/libs/Smarty.class.php on line 1092

 

try to turn of magic_quotes_runtime, it could help solving your problem

 

I am not familar with that issue, however, "Smarty error: [in index.html line 1]:" why are you using .html and not .php?
I would start with that, make sure that you do not have any php code under a .html file.

Another issue that I have had with smarty templates, is that you cannot put in certain code (or at least not the way you normally can for html / php files). Things such as javascript you need to make use of the tags:
{literal}
code goes in here
{/literal}


Not saying that this will solve your problems, but give you ideas that you can look into. I would check these things before anything else.
