# Parse error: syntax error, unexpected ‘const’

 * My website is based on WordPress and the so-called ‘Hygge’ theme. I did no changes
   to the Website, but the website started to display a parse error: “Parse error:
   syntax error, unexpected ‘const’ (T_CONST), expecting variable (T_VARIABLE) in/
   home/customer/www/tracemaker.com/public_html/wp-content/plugins/wp-less/vendor/
   wikimedia/less.php/lib/Less/Version.php on line 11”
 * I updated Wp less but the situation got worse (i.e., I cannot access to the wp-
   admin login page). I suppose that the Wp less plugin is not compatible with the
   latest WordPress version, or with the current PHP version. How can I solve the
   problem?

 * Which version of PHP do you use?
 * I’d suggest you bump it to something more recent, like at least PHP 7.

 * [@oncletom](https://wordpress.org/support/users/oncletom/) I have the same error
   as well. I have PHP v7.0.
 * Why does it say that it expects variable instead of const? Is there something
   simple to fix it?
 * The lines in question are in vendor/wikimedia/less.php/lib/Less/Version.php:
 *     ```
       class Less_Version {
       public const version = '3.1.0';
       public const less_version = '2.5.3';
       public const cache_version = '253';
       }
       ```
   
 * Thank you!

 * I solved it using PHP 7.4.23. Specifically, It seems that there is a minimum 
   and a MAXIMUM version of PHP to work with, i.e., PHP 8.0.010 (and higher) is 
   the problem. Specifically:
    – with PHP 7.133 the website works – with PHP 7.2.34
   the website works – with PHP 7.3.30 the website works – with PHP 7.4.23 the website
   works – with PHP 8.0.010 “Warning: The magic method Vc_Manager::__wakeup() must
   have public visibility in /home/customer/www/tracemaker.com/public_html/wp-content/
   plugins/js_composer/js_composer.php on line 221”

 * I deleted the word “public” from each of the 3 lines and it seems to work on 
   my PHP v7.0.32.
