I've done:
/dev/build/?flush=1
/dev/build/
/?flush=1
/admin/?flush=1
/admin?flush=1
Even trying it on a computer that has never been to the URL.
Same result. I deleted the userform directory and got trunk yet again.
I also get this from time to time, but not always:
Fatal error: Method name must be a string in .../sapphire/forms/Form.php on line 245
I'm at a loss, I'd report a bug, but clearly it is likely something I've got wrong.
Anyideas?
