Udating woocommerce to 1.41, it's not possible to use the checkout button (zur Kasse) anymore. Also the layout of all buttons, tables etc. is broken. Texts are bigger than the buttons etc. Before it looked very professional. Before 1.4 this was much better, beside that shop + single product never called the themes' layout. I hoped to get this solved with 1.4, but now it's really worse.
Furthermore it is not possible to uninstall/delete the plugin, so I can't downgrade to the older version:
Fatal error: Call to undefined function woocommerce_get_page_id() in /data/projects/info-notes/wp/wp-content/plugins/woocommerce/uninstall.php on line 24
Any help would be appreciated a lot! Thank you
