I managed to get nbill installed after wrestling with the ioncube decoder install for a couple of hours, now I am trying to install the AUTHORIZE.NET extension from the nBill extenion installer and I get the following message:
The installation failed because the following file could not be created: /var/www/vhosts/MICHIGANZOOM.COM/subdomains/test/httpdocs/administrator/components/com_netinvoice/admin.gateway/admin.authnet/authnet.php (if this file already exists, try uninstalling the existing extension first).
Prior to this I received a similar message so I changed the permissions to 777 for the administrator/components/com_netinvoice/admin.gateway and components/com_netinvoice/gateway folders. I noticed that the extension install was able to create subdirs in both of these dirs but apparently unable to copy the files needed.
Please help !!
