Cannot Modify Header Information

  • im new at this wordpress thing and im having problems fixing an already worked on site.

    The site is up to date with the PHP version.
    I recently activated the “user registration” plugin because I want to implement user registration on the site.
    After activating the plugin I received the following messages:

    Deprecated: Creation of dynamic property UserRegistration::$form is deprecated in /srv/users/user-centrodeaprendizaje/apps/uai-centrodeaprendizaje/public/wp-content/plugins/user-registration/user-registration.php on line 285

    I don’t understand where these supposed lines of code are and I suspect that if I find them I won’t know what to do with them or how to fix them either.

    Can anyone help me?

  • This is happening because the plugin you have activated is not compatible with the latest version or php. first disable plugin and download latest version of plugin.

    @umarzaki no its not. i just downloaded it and itsa giving me problems. i think i’ll just kill it and hope the next option doesnt give me troubles

    Doesn’t really matter when you downloaded it. The first error Deprecated: Creation of dynamic property. Deprecated items are items that have been removed from the language or library and are no longer supported. The other error can’t update header because it already sent is caused by the first error. When the error is created and echo the error out. It cause php to think you are trying to add to the header that was already created causing that error. umarzaki is correct the problem is with the plugin running outdated code.
