MEFG doesn't work after update -> K2 v 2.7.1

Hello,
I've a problem after an update of K2 and your plugin (i use this version : v.1.0.42).
I've always see my extrafiels but assign to a category doesn't work anymore

I find this notice messages :
Strict Standards: Declaration of K2ElementExtraFieldGroups::render() should be compatible with K2Element::render($layoutId, $data = Array) in /home/xxx/www/plugins/k2/mefgfork2/elements/extrafieldgroups.php on line 14

Strict Standards: Declaration of K2ElementMultiSelects::render() should be compatible with K2Element::render($layoutId, $data = Array) in /home/xxx/www/plugins/k2/mefgfork2/elements/multiselects.php on line 65

Strict Standards: Declaration of K2ElementImages::render() should be compatible with K2Element::render($layoutId, $data = Array) in /home/xxx/www/plugins/k2/mefgfork2/elements/images.php on line 65

On front edit, extrafields are empty

Can you help me please ?

Best regards,
Julien

Hello,

Was the plugin working before the K2 update?
If you can give me access to the backend, this will help me to find out the problem quickly.
