after 2 years of using wordpress, I am quite familiar with this CMS, the process used there are always bugs that I do not know where to place it.
In this article I talk about the font bug in the wordpress admin, my site after a period of use is fine, but then one day, when the error in admin not read Vietnamese words, in the website ngoiaf normal, at first glance I thought thought something faulty in the theme, I backup the old version, perhaps all wordpress data but still not solved.
Then I think of the charset, right is wrong, it is the cause of this error.
If anyone of you have this error in the database to find the table “wp_config” find the line “blog_charset” if its value is different utf8 into utf8 you edit offline.
After you’re done you try to see if there was not okay.
This is the error in the admin, if outside the site fails, the status can have the browser fails with the error is not, nor is it due to this, if you fail to add the file header.php
<meta http-equiv="Content-Type" content="<?php bloginfo('html_type'); ?>; charset=<?php bloginfo('charset'); ?>" />
