:I think I have fixed the problem. It appears that the URL was linked further to a search string that ultimately redirected to the site's home search page. I have no idea how that might have happened. We need to remove those links to "Neola", which has no article of its own on the English Wikipedia, but instead redirects circularly to the Experimental musical instruments page. Another option might be to use an "ILL" (Inter-Language Link) template to link to the article on the Welsh Wikipedia.—
