With Media Translation double slashes may appear in image URLs on translated content

Overview of the issue

When content is translated and the Media Translation plugin is active, the image urls in the translated content may include double slashes. The images still appear as normal, but this can have some unintended side-effects with 3rd parties.

Note, this issue only happens if the default WordPress setting “Organize my uploads into month- and year-based folders” is disabled.

Workaround

While awaiting a fix, the problem can be avoided (for new translations) by editing the file plugins/wpml-media-translation/classes/media-translation/class-wpml-media-image-translate.php

Locate these lines (around line 211):

			$filename          = array_pop( $file_subdirectory_parts );
			$image_url_parts[] = implode( '/', $file_subdirectory_parts );

and edit like so:

			$filename          = array_pop( $file_subdirectory_parts );
			if ( !empty( $file_subdirectory_parts ) ) {
				$image_url_parts[] = implode( '/', $file_subdirectory_parts );
			}
