Hello,
I installed the "Poll" plugin (https://elgg.org/plugins/2472711) on my site with Elgg 5.1.12, and the "Close date" field doesn't work if my user selects Galician as the language (gl.php). However, if I select Spanish for my user, the "Close date" field works correctly.

The specific problem is that when entering any date in that field, if my user has Galician selected (gl.php), no date is saved. However, if my user has any other language selected (English, Spanish, etc.), the date entered in that field is saved.

Could someone help me with this problem? I don't know how to solve it.

Thank you very much.
Best regards.
