The default version of PHP available for sites hosted using UVM Silk periodically updates to ensure UVM sites are using software that receives support and security updates. If your website uses PHP and is no longer functioning after an update, it’s possible that temporarily downgrading to the previous version of PHP will help. To see the available PHP versions and their sunset dates, see the PHP page in UVM’s Silk manual<\/a>.<\/p>\n \t\t

\r\n \t\t\tDowngrading is a temporary reprieve<\/span> \t\t\t \t\t\t\t

\r\n \t\t\t\t\tWhile downgrading your PHP version may help your site work again after a PHP update, it will break again when the version you set it to reaches its sunset date. \t\t\t\t<\/p>\r\n \t\t\t \t\t\t\r\n \t\t<\/div>\r\n \t\t\n
