The Directory of Social Change, which provides training and information for voluntary organisations, acquired the site from GuideStar International in March.
But GuideStar International, which works with organisations in different countries to set up online databases with information on charities, has now announced it has ‘reacquired’ the site.
The move comes less than a week after the DSC revealed that the site’s commercial arm, GuideStar Data Services, had been put into administration.
A GuideStar International statement said the company had "exercised its option to reacquire the GuideStar UK programme".
Asked whether the organisation had paid to reaquire the website and database, a spokeswoman said she was unable to provide any further details.
Spokesmen for both the DSC and the administrator, Maidment Judd, said they were unable to comment.
GuideStar UK holds data on all UK charities in a more searchable form than the Charity Commission database.
GuideStar Data Services also gathers details of non-charitable third sector organisations and has information on 350,000 organisations in total.
