Error Messages after server move

Hi

Our host, Dreamhost, recently moved us onto another server and that broke our website. It turned out that it was the WP-super cache plugin that caused the problem. I was advised to delete it and then reinstall it which I did.

After that the site started to work again, but with the following error messages at the top of each page;

WordPress database error: [Duplicate column name ‘is_featured’]
ALTER TABLE wp_gzpqcn_price ADD is_featured TINYINT( 4 ) NOT NULL DEFAULT ‘0’

WordPress database error: [Duplicate column name ‘title_desc’]
ALTER TABLE wp_gzpqcn_price ADD title_desc TEXT NOT NULL

WordPress database error: [Duplicate column name ‘cat’]
ALTER TABLE wp_gzpqcn_price ADD cat varchar( 255 ) NOT NULL

I contacted Dreamhost again and they said;

“I apologize for the inconvenience. I looked into this for you and see
that the error you are seeing is your code trying to create a table that already exists. You will need to look into your code and see why it is trying to add data that already exists. I hope this helps. If you have any further questions, please feel free to message me back.”

I don’t think I’ve done anything to alter the code and I have no idea how to fix this.

The only thing I can think to do is to export all of the posts and reinstall the theme and wordpress again. This isn’t ideal as we’ve had to do a great deal to customise the site.

If anyone has any suggestions, I’d be very grateful!

Thanks!
