A bit of a faff (technical term) after the server rebuild but the Donations page is back.
Some may notice that it has changed a bit.
The original Donate button was part of a software suite called "Treasury" which allowed donations via PayPal and logged them (and displayed stats). This software is no longer supported by its authors and was a victim of the server change. It won't work on the new version of PHP and there's nobody to update it.
So I have built my own Donate page on the info.sohc.co.uk site and linked it to PayPal in the same way.
