My custom setting for permalinks is "/%year%/%postname%/" - it worked for a while but recently my permalinks are showing as 2011/randomnumberhere, despite the setting still on custom as being year and postname.
Nothing has been changed, no plug-ins added or upgraded etc.
I've also noticed since this happened that wp is really slow and often pages dont load first time resulting in refreshing a few times to get more than a blank screen.
Its not an ISP or server issue as both have been checked out.
Are these related do you think? How can I get the permalinks to display as intended again?
