====== Disable PHP Override ======

You can disable the PHP override in ''.htaccess'' with LiteSpeed Web Server.

''php_value'' and ''php_flag'' can be used in Apache configuration or ''.htaccess'' to override ''php.ini'' settings. However, they are only supported by Apache's ''mod_php'' handler, which is deprecated in most of the control panel systems, having been replaced by php-fpm, fastcgi or lsphp. As a result, if you place ''php_value'' or ''php_flag'' in .htaccess, Apache should return an error. (You can check [[https://support.plesk.com/hc/en-us/articles/213409529-Website-hosted-in-Plesk-does-not-work-Invalid-command-php-flag-or-php-value-|Plesk's documentation]] for details).

You could see any one of the following errors:

  500 internal server error

  503 Invalid command 'php_flag', perhaps misspelled or defined by a module not included in the server configuration.
  The following error can be found in the domain error log in Domains > example.com > Logs:
  /var/www/vhosts/example.com/httpdocs/.htaccess: Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration

  /var/www/vhosts/example.com/httpdocs/.htaccess: Invalid command 'php_flag', perhaps misspelled or defined by a module not included in the server configuration

  /var/www/vhosts/example.com/httpdocs/.htaccess: RewriteRule: bad flag delimiters

  /var/www/vhosts/example.com/public_html/.htaccess: Invalid command 'suPHP_ConfigPath', perhaps misspelled or defined by a module not included in the server configuration. 
  
LiteSpeed Web Server uses lsphp, which supports ''php_value'' and ''php_flag'' usage in .htaccess. You can use these and LSWS will not return a 500 error. LSWS is more tolerant than Apache of these PHP overrides.

In some cases, you may want to disable such PHP overrides in .htaccess for LiteSpeed as well. There is a dedicated Apache directive ''DisablePhpOverride htaccess'', which can be used at the server level ''httpd.conf'' to achieve this.

For example, on Plesk, create a file named ''DisablePhpOverrideLiteSpeed.conf'' in the following directory, depending upon your system:

  * CentOS: ''/etc/httpd/conf.d/''
  * Debian: ''/etc/apache2/conf.d/''
  * Ubuntu: ''/etc/apache2/conf-enabled''

This ''DisablePhpOverrideLiteSpeed.conf'' file should contain the following:

  <IfModule LiteSpeed>
    DisablePhpOverride htaccess
  </IfModule>
