I’ve had to suffer this one for a while. WordPress usually gives you a nice ‘Visual Editor’ for posts, with text formatting options and other toys.
However, mine had long decided to quit the gaff – the toolbar had gone missing, and any text in the post was ‘white on white’ – which is less than useful in most cases. This forced me to disable the ‘Visual Editor’ feature and rely on hand-writing HTML markup to do the ‘pretties’ of bold, italics, bullet points and so on.
But no more! I finally dug up this forum topic which solved the mystery for me, though quite why it requires mucking about with the MySQL records, is a mystery. Still, as WordPress is free, mustn’t grumble 🙂
Oddly, this worked on one site, but failed on another… so your mileage may vary if you are experiencing similar weirdness in your blog 🙂
