ImpEx and database issue

[dchan]

Hi

I do understand ImpEx is no longer a supported plugin but I am still looking for a little help.

I am attempting to import some data from a postgreSql database (huddler).

I have set up a new vbulletin server to do this test.

Windows 2012
PHP 5.6.3
mysql 5.7
vbulletin 4.2.5

Everything seemed to install properly.

I downloaded the latest ImpEx from github, and modified the Impexconfig.php as recommended, put each of the files in the directories that are suggested

I open the admincp and installed the Impex xml.

I now have the import tab on the left. I click through to the import, it asks me for the passcode. I enter it and get a "success" and "redirecting"

And then I get a dialog box that says

mysql error: link-id == false, connect failed.

and here I'm stuck.

I have gone around several directions trying to get past this connect error and I must be missing something somewhere.

I have enabled the Mysql extension even though it's not supported.
I've tried modifying the Impexconfig to try to use mysqli even though that's not supported.

All seem to result in the same error.

can anyone give me some guidance on this. What to try?

Thanks.
