A WhatsApp glitch rendering users' contact list inactive has been fixed in most users' smartphones, according to reports.

The WhatsApp bug led to temporary de-activation of users' contact list with a message "error: unknown". It was reported a few days ago.

The problem was further escalated with a hoax message from WhatsApp CEO, which said they were facing over-usage of usernames and the company intended to check the legitimacy of the users; people were asked to forward the message on threat of de-activation.

Alleged Spam Circulating in Messaging Service

"We have had an over usage of user names on whatsapp Messenger. We are requesting all users to forward this message to their entire contact list. If you do not forward this message, we will take it as your account is invalid and it will be deleted within the next 48 hours. Please DO NOT ignore this message or whatsapp will no longer recognise your activation. If you wish to re-activate your account after it has been deleted, a charge of 25.00 will be added to your monthly bill," reported Firstpost.

This hoax message is allegedly circulated in the name of Jim Balsamic, CEO WhatsApp.

WhatsApp officials have acknowledged the glitch in their messaging app; officials have posted their comments on the company's Twitter page.

A company notification informed users that the spam message circulating was a hoax and assured that the issue will be sorted as soon as possible.

WhatsApp users had faced similar hoax messages in January this year.
