Conclusion: wordpress site folder and associated domain names
wordpress, backed up database
Then another new sites with new domain names, direct compression packages downloaded directly from the official website wordpress site, with no previous Web site folder.
Then import the original database, users set up what are, after using the new domain names can be displayed wordpress initialization interface , set up the database, the user name or something. Then After setting, can not visit the main interface , the entire page is blank.
Access "new domain name / wp-admin" admin interface jump to the old domain name management Web site , I did not set because the old domain name resolution, so the page still does not show up.
At first I thought it was the reason for my browser cache, or so after clearing the cache.
Suddenly I realized, WordPress website folder inside some configuration and domain name associated with it.
After the old domain name resolution, you can display normal wordpress website background. But it is still a problem, wordpress website plug-ins are stored in the site folder, because the current site folder downloaded from the official website of pure catalog, the front view article is no theme effects , and re-install in the admin interface a theme can be.
Of course, the best way is to carry the original Web site folder , so intact the original site migration coming.
