 * Hello I have a problem with Mycalendar With wordpress I have created a website
   in a test environment where everything worked correctly. I tested with a subdomain
   [https://test.mysite.de](https://test.mysite.de) this is on a web host I have
   now removed the subdomain and the site is connected to the database of the subdomain.
   If I now go to the site where the Mycalendar is located I get to see the calendar
   properly, but if I choose another month I get an “Error 0” But on the subdomain
   it does work. What could be wrong
 * the links in the header were still on the test site url

 * Error 0 means that the site failed to load the target page, which usually means
   that there’s a URL problem – you added a statement to this message that “the 
   links in the header were still on the test site url”, and that would mean that
   it was trying to load a page that didn’t actually exist. If you’ve now changed
   the URLs in the new site, then you should be OK.
