Hi, i bought this plugin to a Spanish customer. I need to translate the control panel, edit the translation files but don't see changes, How I do that?
Which tool have you used for the translation? For poedit:
Once you have created the necessary .po and .mo files with the correct name and put them in the correct folder, you need to switch the language of the wp-admin to that language. FPD will always display in that language.
