I own the site www.poshpigtails.com. It has been made unusable (it was working perfectly fine) by my web guy because he decided to upgrade the main database and I am now getting this error msg:

1054 Unknown column 'p.products_id' in 'on clause'

He wants to charge me more than he originally charged me to set up the site for this 'forced upgrade'. I am a stay at home mom of three and do not have this money and now I have no business either. Any advice and help would be appreciated. I do not know any coding etc. so it is unlikely that I can fix it myself.

Thanks in advance for any and all help!
