站点移动后WordPress帖子/页面内容空白在后端

Question

After moving a WordPress website from one server to another I have encountered an odd issue. Everything works great, until I go edit any post or page and I am presented with an empty content box on the backend. (see image).

All of the posts and pages are displayed properly on the front end except that there are strange characters in the content (see image).

If I try to republish a post, then the empty content saves over the hidden content and the post becomes empty on the front end.

I disabled all plugins and switched themes which changed nothing.

Did I corrupt my database on transfer or is there some other reason that might have caused this?

Has anyone else run into this?

Answer 1

The problem turned out to be that DB_CHARSET and DB_COLLATE were both set to '' (empty string) in wp-config.php. I updated them to the following values and all issues were resolved:

define('DB_CHARSET', 'utf8');

define('DB_COLLATE', 'utf8_general_ci');
