PHP problem ( Invalid argument supplied for foreach)

Prilikom otvaranja nekog linka koji ne postoji na stranici li je skriven za clanove javlja se ova greska:

[Fri Jan 27 22:55:32 2012] [error] [client XXX] PHP Warning:  Invalid argument supplied for foreach() in //wp-includes/query.php on line 2746, referer: http://m.facebook.com/l.php?u=http%3A%2F%2Fwww.XXXX%2F&h=lAQHf0vsk&no_warn_external

Mislim da je problem sa .htaccess ali ne znam gdje tacno.

ne vidim kako bi mogao bit problem u .htaccess
gore piše da je problem u:
//wp-includes/query.php on line 2746

ovako nešto bi išao kod… foreach($array as $element)
problem je jer ovaj $array ustvari nije array

na ovom linku ima nešto o tome

http://php.syntaxerrors.info/index.php?title=Invalid_argument_supplied_for_foreach

Kada sam rekao .htaccess onda sam mislio na pravilo o Permalink Settings .htaccess se editovao za pravila o linkovima i ove greske su se svele samo na nepostojuce linkove dok su prije bile za sve linkove.

// Always sanitize
		[color="Red"]foreach ( $this->posts as $i => $post ) {[/color]
			$this->posts[$i] = sanitize_post( $post, 'raw' );

to je warning, ja se oko toga ne bi previše uzrujavao
ovdje ti izlistava neke linkove u foreach petlji, mislim da ti problem kad u ovom $this->posts imaš samo jedan link, a ne više njih što se očekuje
ako se to desi petlja svejedno odradi ono što bi trebala ali izbaci onu poruku a na jednom mjestu nije bio očekivani argument

mislim da ne bi dobivao warning da prije petlje staviš provjeru ako je $this->posts array pa onda izvrši kod samo jednom bez ulaska u petlju, ali kažem… ne znam dal to ima smisla
