MASS change uploaded facebook / twitter url's
I uploaded about 1k new listings and I was notified that none of the facebook and twitter links work due to a MAJOR upload error (which was not explained how to do). IE: I put in the CSV file
https://twitter.com/LocalDHub to upload not knowing I needed to remove
https://twitter.com/ .
Now all the links show
https://twitter.com/https://twitter.com/LocalDHub.
How can I remove one set of
https://twitter.com/ on a mass scale (Hopefully all at once)
