In the customer account interface there is My activities section.
When the customer selects the ticket there is an option add to conversation, for some reasons this stopped to work and the field does not allow to add any text. Can anyone help? - it seems to be an issue with a script, however when we remove it in full it doesn't make any difference.












Appreciate you taking the time to share this with us Matt :)
Glad you were able to track down the issue.
Cheers!
