That's quite interesting you had to put the files in the skin1/customer folder, I've not seen that issue yet
Thanks for the catch on the empty pages var, I just added the XC SEO bit last night, I'll make that correction. Cheers
UPDATE:
I updated the zip with changes that should correct similar errors for others, it's been updated in the first post
This isn't a major or required update, so the 8 people that downloaded this already, you'll likely be fine
