No, was not sure where to find them for the installer… but will look now… but i did open that DB the WHMCS was supposed to use and the table that was supposed to have the first admin user in had nothing in it… so the error message was indeed correct - unable to create the user… that being the case - i created a user in the DB, but then go that white screen that you sometimes get with WHMCS when it is not happy, at that point i realised i was really wasting my time as the script really was not going to work and i installed it manually and used a domain based DB, so i will get sensible backups… i presume that the DB will be dumped and recoverable if it is attached to the domain…
i Will look in that particular log - but i will not encourage anyone to use that script as it seems quite broken just now.
After i installed it manually, i did not try again with the script, as WHMCS needs you to have a license - i am not sure how this script is supposed to work, i guess i would like to see some documentation somewhere.
I suppose i could open the script and see if there are notes in there… but WHMCS is not something i will be updating using virtualmin - i have moved all the management stuff onto its own server (running GPL) but WHMCS needs you to be logged into your licence account on their server to download upgrades, and it is a pretty manual process. Given the sort of data that WHMCS contains - i would rather be doing it manually and know what is going on.
