Builder Known Issues
Error message /modules/class.module.php:153:Call-time pass-by-reference has been removed
This error message shows because your server is (now) running PHP 5.4 and an outdated version of Builder theme, or the Builder plugins (Builder Stylemanager and Builder SEO) is active on your site.
Builder theme, and Builder plugins (Builder Stylemanager and Builder SEO) need to be updated to the latest version to be compatible with PHP 5.4.
If you have a current subscription, you can download Builder, Builder Stylemanager and Builder SEO from your membership page. Unzip these files to a known location on your computer. Then, you can upload the (unzipped) theme files to the
wp-content/themes/ (or the plugin files to the
wp-content/plugins/) folder using FTP or your hosting cPanel. You should Rename the existing theme or plugin folders on your server first.
Update existing code
Replace all instances of &$ with $ in all the Builder theme and Builder plugin (Builder Stylemanager and Builder SEO) php files. Make a backup of the theme and plugin files before you do.
If that doesn't resolve this, and you have a current subscription, for further assistance, please post a support request in the Builder support forum: http://ithemes.com/forum/forum/64-builder/
