When attempting to send an SMS in 4.7.23 no text area appears in the dialog for entering the message. I DO get the 'From', 'To', 'Name; and 'Template' widgets. If I press send SMS I get the error 'Please provide Text message.'
This was working last time I used it (maybe 4.7.21?)
I have tried this with different browsers and different SMS providers to no effect. The problem arose with v2 of the clickatell extension and upgrading to version 3 made no difference.
Suggestions appreciated
