Help, my site is suddenly populated with weird characters, like this:
â€œDo what you love and do it often,â€ â€œIf you donâ€™t like your job, quit,â€ and â€œTravel often; Getting lost will help you find yourself.â€
What do I do to remove it?
It appears that the site is still using the Unicode character set from the page header, but the database may have been corrupted. Ask Linode for a backup restore and/or if they changed anything with their MySQL servers.
If you don't run your own regular database backups, you should. Try WordPress › WP-DB-Backup « WordPress Plugins.
You can also use phpmyadmin at Linode to check the collation of the database and repair it. Or use WordPress › Portable phpMyAdmin « WordPress Plugins from inside the WP admin.
You can try commenting out the encoding type in the wp-config. Sometimes that works.
