    I was using this then my site when down saying: there was some undefined value “boolval()” in admin-css-mu/admincssmu.php on line 275 so I had to deactivate the plugin via FTP to access my admin area.

    When I try to reinstall I get this error:
    Installation failed: <!DOCTYPE html> <!–[if IE 8]> <![endif]–> <!–[if !(IE 8) ]><!–> <!–<![endif]–> LiveSite Pack ‹ Ascendancy Consulting — WordPress addLoadEvent = function(func){if(typeof jQuery!=”undefined”)jQuery(document).ready(func);else if(typeof wpOnload!=’function’){wpOnload=func;}else{var oldonload=wpOnload;wpOnload=function(){oldonload();func();}}}; var ajaxurl = ‘/site/wp-admin/admin-ajax.php’, pagenow = ‘toplevel_page_live-site’, typenow = ”, adminpage = ‘toplevel_page_live-site’, thousandsSeparator = ‘,’, decimalPoint = ‘.’, isRtl = 0; Fatal error: Call to undefined function boolval() in /home/www/ascendancyconsulting.com/site/wp-content/plugins/admin-css-mu/admincssmu.php on line 275

    It worked 2 weeks ago. What’s wrong?

    Hey @seanbanksbliss,

    It looks like your server us using a PHP version lesser than PHP 5.5. boolval() is a function that came in PHP 5.5 and the latest version of Admin CSS MU uses this function for couple of option checks.

    Recommended solution: Ask your host to upgrade the PHP version to the latest (ver 7.1). Latest release addresses a lot of security issues and there is noticeable improvement in performance.

    Quick fix: Install version 2.2 of Admin CSS MU and upgrade after your host upgrades PHP.

    Please remember to take a full backup of your website before upgrading PHP especially if you use old unsupported plugins. Some functions are depreciated in PHP 7 and this might break some old plugins.

    Hope this helps.

    Hey @seanbanksbliss

    I am closing this issue since there is nothing more I can do at my end. If the issue persists even after upgrading PHP or downgrading plugin, please let me know.

    Hope you have a good weekend ??

    Hey @seanbanksbliss

    Here is an interim solution if you do not want to upgrade PHP. Add this to your theme’s functions.php

    /**
 * Get the boolean value of a variable
 *
 * @param 	mixed 	The scalar value being converted to a boolean.
 * @return 	boolean The boolean value of var.
 * @refer	https://php.net/manual/en/function.boolval.php#114013
 */
if( !function_exists('boolval')) {
    
    function boolval($var){
        return !! $var;
    }
}

    This will let you use the newest version of the plugin with all the new features.

    Regards,

    Backward compatibility for PHP versions lesser than PHP 5.5 is included in the latest release Version 2.5
