The text widgets are not working on my WordPress install. I can add them and they save and display on the front end, but when I refresh the page I don't see them any more and they vanish from the front end. Explanations welcome. I've not moved the install or anything which seems to be a common problem here. I think I may have had to have changed the domain name as there was a line in the functions.php theme file that set the URL, but that's all. Question is, how can I reset this back?
