I updated a Craft 2.6 installation to the latest 2.6.x and suddenly I get an error when saving a user's profile on the frond end:
mb_detect_encoding() expects parameter 1 to be string, array given /data/sites/web/boumaticdevbuthostcom/subsites/corporate-web.boumatic.dev.buthost.com/craft/app/vendor/elvanto/litemoji/src/LitEmoji.php(108)
However, nowhere on that page has an emoji been inserted in any input fields or anything.
I hope somebody can help me with this as it is an urgent issue.
I just tracked down the problem to this input field:
<input type="hidden" name="fields[gdprPermissionsList][permissionSales][type]" value="permissionInfo">
Which is quite weird as it does the exact same thing as 3 other fields on that page which work fine.
