unexpected integer “1” wp-includes/pomo/mo.php on line 105

Checked on my WordPress site today to find an HTTP 500 error.

2022/04/12 02:12:05 [error] 878#878: *5 FastCGI sent in stderr: "PHP message: PHP Parse error:  syntax error, unexpected integer "1" in /var/www/domain.net/htdocs/wp-includes/pomo/mo.php on line 105PHP message: PHP Parse error:  syntax error, unexpected integer "1" in /var/www/domain.net/htdocs/wp-includes/pomo/mo.php on line 105" while reading response header from upstream, client: 162.158.62.41, server: domain.net, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php8.0-fpm.sock:", host: "domain.net"

Line 105 in that WordPress file is:

$total                     = count( $entries )   1; // All the headers are one entry.

WordPress version 5.9.3

PHP version 8.0.3

Answer

My local wordrpess has this as that line…

$total                     = count( $entries ) + 1; // All the headers are one entry.

I think your file has been tampered with
