Extremely slow index page load in my forum

[ferns.mark77]

I use MyBB forum 1.6.4. I am facing a huge 20 seconds lag in loading only the index/home page of the forum.

http://www.protastic.x10.mx


I have redirected the above link to: http://www.protastic.x10.mx/forum/ in the cpanel- Redirects option.

When i installed it, it loaded perfectly[fast]

But now, after adding and disabling plugins, this problem occurs.
Please help me out here. Is is the server redirection or server side problem or just the problem in the MyBB and the additional plugins added?

Thanks.

Try disabling all of your plugins and poking around your forum then. If it runs faster, then it's a plugin

i disabled all the plugins except for 'facebook connect' and 'advanced sitemap'. i dont think that these 2 create any problems in the site.
the thing i dont understand is that only 'index.php' has the the problem of loading. the other pages within the forum are loading perfectly faster than expected.

please visit and see the index page.

some other pages within the forum that load quickly are...

The problem might be the malware that piggy-backed onto your index.php file; open it in cpanel's code editor and look at the bottom.

You'll want to fix that part for sure - most antivirus software, including mine, is outright refusing to open the page because of it.

i dont know whats wrong with the index.php. is it possible for a 'malware to piggy-back' on a read-only file.
plus i have scanned my site here :http://www.urlvoid.com/ , and the status is CLEAN.

Even my antivirus [ESET Nod32] blocked my site, i had to put it in the exception list. I dont understand whats going wrong here... why the problem in the index page?
