Call to undefined method Grav\Common\Page\Page::getContentMeta()

After updating to latest version shortcode-core (i guess) gives that error.

Location: /user/plugins/shortcode-core/shortcode-core.php
Highlighted line: // get the meta and check for assets
$meta = $page->getContentMeta();

Git issue: https://github.com/getgrav/grav-plugin-shortcode-core/issues/9

upd: shortcode-core for sure, uninstalled the plugin and site is back to work. After installing it back again, got the same error.

As replied on the issue, update Grav

Tried. It gives "Nothing to update"

Wicked, selfupgrade command updated the grav. Now all works fine, thank you!

P.S. I See, my mistake, update and selfupgrade just different type of commands.
