Database connection problems

Hi there,

I have a Perch site that is running perfectly locally and was also running fine on the live server until the client carried out a server migration (without telling me!). Now on the new server there are what appear to be some database connection issues and I would really appreciate any help with this or any advice as to what I can tell the admins of the new server and hosting.

When I try to login to the Perch admin as I get the following errors:

Warning: mysqli::mysqli(): (HY000/2002): No such file or directory in /var/www/html/perch/core/lib/PerchDB_MySQLi.class.php on line 27

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/perch/core/lib/PerchDB_MySQLi.class.php:27) in /var/www/html/perch/core/lib/PerchUtil.class.php on line 194

Warning: mysqli::ping(): Couldn't fetch mysqli in /var/www/html/perch/core/lib/PerchDB_MySQLi.class.php on line 62

On a page within the site I get the following output from debug:

I've also run the Perch compatibility test on this new server and I get the following errors on screen:

This is then followed by a Perch compatibility notice saying that the test has been unsuccessful with the reason that "Perch needs at least MySQL version 5.0 for new installations. You have ."

The new server is running MySQL 5.6.30 though.

If any of the above makes sense and you can give me some advice, it would be very much appreciated!

Thanks,

Simon
