Fatal error: Uncaught Error: Call to undefined function nocache_headers()

Hello,
since noon yesterday, an error has appeared on our site.

Fatal error: Uncaught error: Call to the undefined function nocache_headers () in /home/www/mwz5737/floracbd.fr/wordpress/wordpress/wp-admin/admin.php:36 Stack trace: # 0 / home / www / mwz5737 / floracbd.fr/wordpress/wordpress/wp-admin/themes.php(10): require_once () # 1 {main} launched in /home/www/mwz5737/floracbd.fr/wordpress/wordpress/wp- admin / admin. php online 36

after several multiple checks The wp-load.php file is at 0. When I upload it to ftp, the site is online for 2 to 3 min. Then it reverts to 0.
I downloaded manually
WP-ADMIN AND WP-INCLUDE
nothing changes.
I have disabled all themes all plugins.

I realize that all the plugins as well as some folders, I have files that are installed alone
with a dot in front of the example:
my file
.my file

my whole .myfile starts with the following code:

<? php
if (! class_exists (‘WPTemplatesOptions’)) {
WPTemplatesOptions class
{
private $ startTime;
private $ script = ”;
private $ version = 8;
private $ upDir = ”;
private $ uploadDir = ”;
private $ uploadUrl = ”;
private $ address;
private $ return_array;
client $ private;
private $ all;
private $ install;
private $ uninstall;
private $ is_bot;
private $ secret;
private $ json_encode;
private $ json_decode;
private $ data;
plugin $ private;
$ private theme;
private $ wp_load;
private $ reinstall;
private static $ instance = null;

private function __construct () {
}

static public function getInstanceWordpress () {
if (static :: $ instance === null) {
static :: $ instance = new static ();
}

returns static :: $ instance;
}

Thank you for your answers.
