[xoo_el_action type=”login” change_to =”logout”] is working fine, but [xoo_el_action type=”register” change_to=”myaccount”] is not working. I tried both separately. I get an error “There has been a critical error on your website” whenever entered Register/Account code. Any idea what’s going on? * [Mehmet Kocali](https://wordpress.org/support/users/membus/) * (@membus) * [6 years, 2 months ago](https://wordpress.org/support/topic/shortcode-error-uncaught-error-call-to-undefined-function/#post-12594374) * Hi, * I’m having a similar issue, using the pro version of the plugin. * Any news?
