I use the Pro Site plugin together with the WHMCS MU PROVISIONING Plugin. My client's site has been disabled for non-payment. I have now reactivated the client's site, but when I try to access the site WordPress informs that "This site is no longer available."
When I access the administration area of my network the site is active again.
I can usually access the control panel after reactivation.
I can access other pages of the site, but the initial page continues with the message "This site is no longer available."
Please help me solve this.
