I noticed a new shortcode wrapping my form labels: [cred_i18n] but I can't find any documentation on this on your website. Only instructions for wpml-string.
Is [cred_i18n] deprecated? If not, what are the parameters and where will it look for .po files?
This shortcode was introduced in Forms 2.6, part of the round of plugin updates that brought major improvements to WPML translation workflows for Toolset.
Those shortcodes are to help locate the text in the form when it is scanned for strings. It is no longer necessary to use wpml-string shortcodes to make text available in WPML String Translation.
