Dreamhost has just performed a compulsory upgrade to PHP 5.6 and, not surprisingly, some scripts have broken. I will do my best to fix the problems today, but for the moment it might be best to refrain from purchasing anything.
UPDATE: 4 MARCH 2016 - I seem to have corrected the problem with several patches and minor code adjustments, and as far as I can tell the store is working normally. It is slow to respond but then it always has been, unlike the Beauties in Bondage one. The two are essentially identical and the B2B one is on the faster server, so I don't know why this happens.
Anyway, all should be well, but let me know if you run into anything unusual and I'll help.
Dave.
