[Solved] Blank screen after upgrade from 1.3.2.3 to 1.4.3 and php errors

[starxox]

Hi there

I've recently tried an upgrade (thankfully on a test version of my shop) and I just get a blank screen when I try and access the front office to complete the installation.

I checked the error log and am getting the following errors:


[04-Jul-2011 21:55:56] PHP Warning: mysql_connect() [function.mysql-connect]: Access denied for user ‘stormjew_test’@‘localhost’ (using password: YES) in /home2/stormjew/public_html/test/classes/MySQL.php on line 34
[04-Jul-2011 22:13:35] PHP Warning: Invalid argument supplied for foreach() in /home2/stormjew/public_html/test/classes/Link.php on line 206
[04-Jul-2011 22:13:35] PHP Fatal error: Cannot access empty property in /home2/stormjew/public_html/test/classes/FrontController.php on line 232
[04-Jul-2011 22:13:45] PHP Warning: Invalid argument supplied for foreach() in /home2/stormjew/public_html/test/classes/Link.php on line 206

[04-Jul-2011 22:13:58] PHP Warning: Invalid argument supplied for foreach() in /home2/stormjew/public_html/test/classes/Link.php on line 206

and it goes on like that.

I'm not sure if I've made a mistake in installing a test version, or if it is a problem with the upgrade and I don't know PHP so can't work it out.

Please note that I have put this query here http://www.prestashop.com/forums/viewthread/117245/upgrading_prestashop/how_can_i_install_a_test_version_of_prestashop_to_check_if_my_shop_will_upgrade_ok

But not getting any help, maybe because the title doesn't relate to my current problem. If I get help here then I will mark the other thread as solved.

Please please can someone try and help me, I'd really appreciate it.

Many thanks

Louisa

Well I had to pay for help on this one, which is a shame since it was a really easy fix if you know a little bit about php and so on (which I don't!)
