заметил что после загрузки файла на ftp удаляеться часть кода:

if ( is_array( $data ) && count( $data ) )
			
				foreach( $data['open'] as $id => $val )
				{
					$o = $data['open'][ $id ];
					$c = $data['close'][ $id ] - $o;
					
					/* Prevent unclosed tags from breaking this */
					if ( $o < 1 || $c < 1 )
					{
						continue;
					}
					
					$slice = substr( $content, $o, $c );
	
					$_origLen = strlen( $slice );
						
					if ( $passLevel == 2 )
					{					
						//* No linkify */
						preg_match_all( '#<a(?:[^>]+?)href=["']([^"']+?)["']([^>]+?)?>(.+?)(</a>|$)#is', $slice, $urlMatches );
				
						/* Finish up URLs and such */
						for( $i = 0 ; $i < count( $urlMatches[0] ) ; $i++ )
						{
							$raw  = $urlMatches[0][ $i ];
							$url  = $urlMatches[1][ $i ];
							$text = $urlMatches[3][ $i ];

про такую штуку как СПОЙЛЕР не слышали?

права на папки проверьте, кодировку БД так же посмотрите, возможно вы скачали поврежденный архив
