Hi!
There is a very specific rule in your theme’s stylesheet that targets WebKit based browsers (such as Chrome) and that is causing the problem here:
select,
input,
textarea {
-webkit-appearance: none;
-webkit-border-radius:0;
border-radius:0;
}
(Which you can find around lines 597-603 of your theme’s style.css file.)
You would need to override this. One way could be to simply add an extra rule at the bottom of that same file or else wherever the theme vendor recommends (to avoid the change being erased on future updates):
.tribe_community_edit input {
-webkit-appearance: normal;
}
