Strings outputted by WordPress themes or plugins are called Gettext strings. Translating these types of strings through TranslatePress can be unnecessary if they are already translated or you plan to translate them using the .po/.mo translation file system. So, you might want to disable their translation.
Disabling this feature of TranslatePress can improve the page load performance of your site in certain cases.
All you have to do in order to disable the translation of Gettext strings is download and activate the following plugin. No other setting is necessary.
