I’m not getting notifications from WP support for some reason. What version is your site running? If it’s not 1.1.0 the latest, please try this latest version and tell me if that resolves it. * Thread Starter [Fernando Lopes](https://wordpress.org/support/users/fernandolopes/) * (@fernandolopes) * [9 years, 4 months ago](https://wordpress.org/support/topic/error-adding-post-type/#post-8687087) * I’m sorry for the delay. The error was because the server had an old version of PHP. I upgraded to PHP 7.0 and the error disappeared.
