Not a good idea to upgrade WordPress at half past midnight when you’re tired and already fed up. I kept getting errors about unexpected T_ENDIFs, whatever they are. For some reason, it only worked when I switched to the Iyonix and uploaded the files again using FTPc. Score 1 for RISC OS!
And the clocks have just gone forward, so it’s now 2am, not 1am! I’m going to get even less sleep than I normally do.
