Issue with Google Index checker - one of our vendors that checks whether the website is indexed by Google is facing downtime. Due to this the domains are not being checked for indexation. As soon as they fix this, we will remove the message. Sorry about this.
Go ahead and purchase the plan you want to upgrade or downgrade to and purchase it. When done, email us at support@domcop.com and we will cancel the old subscription and give a pro-rated refund for it
