Simple fix! Install the plugin Say What? and go to the Tools->Text Replacement page. Add a new replacement and enter The user did not enter a description yet. for the original text, userpro for the textdomain, and enter your new text in the appropriate field.
Hey Kris, that’s an understandable sentiment, but Say What? has virtually zero overhead. I’d recommend giving it a chance. After all, it’s as close to an ‘official’ option as WordPress has for single-string translations.
themedutch is correct. WordPress allows translation through the use of a PO/MO file. This however, is a more complicated procedure which is outlined here and requires access to either the command line or the use of a plugin to generate the translations. Say What? is the easier option when you’re only looking at translating a single string rather than generating a translation file for the whole plugin.
