title: Is wordpress caching widgets?
body: <p>I have to move a wordpress site under an other domain (foo.com => foo.hu) so it's needed to update the links on the site. I wrote a script which replaces the tld in the database in the posts/options, but when I check the site I see no widgets on the sidebar...</p>
  
  <p>I tried to find something about it's caching (based on md5 hash or like that), because if I replace the tld to the original in the text widget everything is fine again. But regarding to the wordpress documentation (and some forums) there's no permanent caching built in.</p>
  
  <p>So my question is, how can I modify the contents of text widget from the outside?</p>
  
  <p>I really don't want to do it by hand...</p>
