Working through a WP book, I followed instructions to create a simple theme. Activated this new theme. Got 'parse error' and could not get back to dashboard. Locked out. I reloaded WAMP and WP. That worked of course.
So - How do you recover from such a locked out situation without reloading everything?
All I could think of was to replace my new index.php with the TwentyEleven index.php, and hope I got back to dashboard to re-activate working theme . . . .
Doesn't this situation occur with theme developers all the time? What do they do?
