Hello MJ,
On the product page, the word “Participant #{nb}” can be changed in the form editor, in the “Participants fields” options.
In cart, the words “Participants”, “Participant #%s” and the sentence “The desired quantity doesn’t match the number of participants. In order to change this item quantity, add it back to your cart with the desired number of participants.” can be translated thanks to this file: wp-content\plugins\ba-advanced-forms\languages\ba-advanced-forms.pot
Open this file with POEdit, make your translation, and save it here with those exact names:
wp-content\languages\plugins\ba-advanced-forms-xx_XX.po
wp-content\languages\plugins\ba-advanced-forms-xx_XX.mo
where xx_XX
is your locale code (e.g.: fr_FR for french, de_AT for German from Austria…)
Then make sure that your site language corresponds to that code in your dashboard > Settings > General > “Site language” option.
Please contact me by email for any questions related to add-ons, www.remarpro.com doesn’t allow it.
Regards,
Yoan Cutillas
