polylang DEACTIVATE bug

Hi there,

it seems impossible now to deactivate Polylang plugin at my website.

in the Plugin page clicking at DEACTIVATE for Polylang just a blank white page appears with the this url.

****
wp-admin/plugin-install.php?tab=plugin-information&plugin=polylang&TB_iframe=true&width=600&height=550

Is there are any way to uninstall polylang and perhaps you have some suggestions on how to migrate from polylang to wpml?
I was really happy with this great plugin until we implemented woocommerce shop, now woocommerce service pages (cart, payments…) seem not to be translatable.

thank you in advance!
