Website & admin panel doesn't load suddenly, no data received message on Chrome

[vanillafrog]

All of a sudden, my site has stopped loading entirely (or loads very slowly). Both frontend and admin panel doesn't load.

 

In cpanel, I checked the error logs and got this:

 

[Wed Aug 28 08:40:23 2013] [error] [client 220.255.1.18] PHP Warning:  mysql_close() expects parameter 1 to be resource, null given in ........./public_html/track.php on line 84

 

There are 8 errors, since around midnight.

 

Contacted host and they said it was CSS loading issues caused by jquery.autocomplete.css.

 

No upgrades, changes to any files, new installations were made.

 

Can anyone help?

 

Website: www.bagcharmlove.com (it's working fine now after I did a rollback, still wanna know why it happened though)

Css? Of course not. That's a mysql connection issue, or so it seems. Anyway, is that file they mention located inside js\jquery\plugins\autocomplete?

 

Also, what is that track file? Prestashop doesn't have it by default

i checked your website, for me it works very well, first load time about ~2sec, any other about 1sec

i can record video if you want

 

or maybe you fixed something?

Didn't think it was the CSS either. They gave me this link: http://www.webpagetest.org/result/130827_2X_MXN/1/details/

I'm not sure if that error log is the cause of the issue too. I'm also not very sure what track.php is.

 

I have asked the host to return the site to yesterday's backup, and this has somehow fixed the problem (at least for now).

 

But I would still like to figure out what went wrong in case this happens again.

Also from my knowledge, I have checked and no files was physically changed on that date except a few newsletters sent out.

I have the same issue. Trying to fix "SIRET issue" to allow people to enter any company code they want, I changed file Validate.php in directory classes. 
line 1042:

if (Tools::strlen($siret) != 14) 

I changed to

if (Tools::strlen($siret) != 100)

.

Saved, refreshed page and got frontend of shop completely blank (ok, white) screen. admin also does not load.

Please advise.
