For Welsh, the link from the 'donate' button in the sidebar now points to the banner still points to the Welsh version. But the link from the central banner still goes to the English landing page here

When this was last discussed (see Dec 5 postings), it was left with Joseph Seddon to fix the link from the central banner and the 'Read now' image. But unfortunately, he doesn't have the time to fix this now, so we will just have to wait until he does have the time (in a week or so, I believe) or someone else comes forward who can do it.
Have just checked yi - same situation.
