Problem: The client is unable to display an English version of the logo on their bilingual site (Greek default, English secondary) after moving from a temporary domain to a live site. The client has tried updating the logo URL and clearing the cache but cannot find the new image URL in the string translation. Solution: We recommend searching for the image ID in the admin strings section and translating it. This involves adding a translated image ID for the English version. Each image in the media library has an ID, which can be translated following the steps in our documentation on translating theme options: https://wpml.org/documentation/getting-started-guide/string-translation/how-to-translate-theme-options/
