Krikor Hello, thanks for agility.
Yes, I found a relationship with a plugin developed according to Example K2 plugin (
getk2.org/extend/extensions/90-example-k2-plugin-for-developers).
When you enable this plugin, each ENTER, regardless of what the field is, the form submits the data and clears the fields.
I am now trying to figure out how to block this action.
Any suggestion?
