The south coast club has failed to make monthly payments to its players several times this season while the Premier League diverted most of their recent seven million pounds television income to clubs they still owe transfer fees.
One piece of good news this week for the Premier League's bottom club was the lifting of a transfer embargo meaning they can make loan signings as they try and escape relegation.
The website resumed service shortly before 3pm on Thursday.
