I just want to modify the success message that's displayed by the signup form. I've tried to follow the suggestions in other threads about updating the po file and generating an mo file. I've never done this before, so I'm not sure if I'm doing something wrong, but I'm having an issue with the file. I generate the file locally on my mac using POEdit as suggested, and then commit to the git repository, which then deploys it to a development server.
The file works great locally, but the very same file displays incorrect messages on the development server. For instance, instead of saying "That email address is invalid" it says something about interest groups.
Is there an issue with generating the files and using files on different operating systems?
Also, as I'm not familiar with these po/mo files, am I correct in assuming that you won't overwrite them when you do a plugin update? We have a somewhat automated update process, and I am extremely hesitant to update plugin code, for fear that I'm going to have to manually apply patches to the plugin after updates.
