I have the plugin up and running on Pinboard. All steps successful, but still unable to see translations on my page.
What I have done so far:
Add new language Fr. Canadian
scan plugin (i.e. contact forms)
edit english text to french manually and save
.....and then checked for translation on the contact form that is on my site already. No translations showed up. Also, I have previously add some translations manually within the plugin. Not sure if this will cause a problem with your plugin.
???? Am I missing something.
