redirect – 503 Service Unavailable error was encountered


When I try to upgrade PHP to version 7.4 or 7.3, I get the following error:

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.

I tried to rename plugins folder and switched back to old PHP version and deactivated all pluigns, But still the same.

I activated twenty twenty-one and twenty twenty themes from WordPress, But still the same.

Finally I tried to logout and upgraded to PHP 7.4 and I could see the homepage. But when I try to visit any other page like /wp-admin or pages in the menu like /contact, I get the same error again.

I think it could be from .htaccess. Here is the code there:

RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

<IfModule mime_module>
  AddHandler application/x-httpd-ea-php74 .php .php7 .phtml
# php -- END cPanel-generated handler, do not edit

I tried to comment the first part which redirects to https:

#RewriteCond %{HTTPS} off
#RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
#RewriteCond %{HTTP_HOST} !^www. [NC]
#RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

And when I tried to visit, I got that same error.

When I tried, it loaded fine. But not other pages only homepage
