 ### Do not translate internal errors
 
 Do not translate internal errors, or log messages, or messages that appear on the RPC interface. If an error is to be shown to the user,
-use a generic message, then log the detailed message to the log. E.g. "Error: A fatal internal error occurred, see debug.log for details".
+use a translatable generic message, then log the detailed message to the log. E.g. "A fatal internal error occurred, see debug.log for details".
 This helps troubleshooting; if the error is the same for everyone, the likelihood is increased that it can be found using a search engine.
