Plugin Duplicator D'base Errors

Hi all,

I know im not the sharpest pencil in the box and this has had me stumped for a couple days now..

I have 2 sites live. I have completely rebuilt one on my Ampps multi site localhost install and am ready to upload & ‘live test’ it.

Excellent News – I used Duplicator to successfully clone the live sites to my Ampps localhost.

Not so excellent news – Created a new d/base & user in Hostgator Cpanel. I also created a subdomain to ‘live test’ the new site on Hostgator server prior to final change over / release.
U/l the install.php & archive files into the subdomain folder, run the Duplicator Install. It Connects, Deploys(Step 1) & Updates(Step 2)… all with with no errors or warnings.
At Test Step 3 however, it falls over.
3.1 Install report = shows 0 errors & 0 warnings
3.2 Save permalinks = Error establishing a database connection
That is as far as I have got on many separate occasions now.

I then used the same 2 Duplicator files to successfully create a 2nd copy on my localhost, so I must presume the files are fine.

I have tried leaving the default hostname as ‘localhost’ and have also tried using the Hostgator Configuration Settings… same D/B Error on all occasions.

Like I said, im not too techie so do not know what other info to include.

All suggestions greatly appreciated.

Cheers
Joe
