Ne može se pristupiti sajtu sa gugla

Pozdrav ljudi, može neka pomoć?

Sajt se nalazi na domenu http://agroinfotel.net/ Već nekih 20 dana sajtu se ne može pristupiti sa gugla. Gugl ga prikaže u pretrazi, ali kada se klikne otvori se bela prazna strana. Inače kada direktno ukucam adresu onda otvori sajt.

Reinstalirao sam wordpress, plagine sam sve gasio i opet isti problem. Kada pokušam pomoću All in One plagina da generišem XML sitemap pojavi mi se sledeća greška:
This page contains the following errors:
error on line 2 at column 6: XML declaration allowed only at the start of the document
Below is a rendering of the page up to the first error.

U php_error logu najčešće prijavljuje sledeću grešku: PHP Warning: Error while sending QUERY packet. PID=64977 in /www/webvol9/2o/4tqhn76vdmr8sej/agroinfotel.net/public_html/wp-includes/wp-db.php on line 1877
