install/upgrade_run_2.1.27.php fails (Probably misnamed function call to mysql_num_rows())

[wirerydr]

Steps to reproduce

1. Start an upgrade to development commit 20b5a5a.

Expected behaviour

Upgrade should complete successfully.

Actual behaviour

On screen Step 4, upgrade_run_2.1.27.php fails to complte. Instead it displays "Loop #1 is now running ..." with a spinning gear forever.
An error appears in the httpd logs:

An examination of the TeamPass codebase indicates that this is the only call to mysql_num_rows() in the entire project. However numerous calls to mysqli_num_rows() exist. Presumably this is a simple function-name typo.

Yes you are right.
I have included just now for robustifying the upgrade and introduced this mysql function instead of the mysqli.
What I don't understand is that no errors were shown during my test ...

Re-tested by upgrading to development commit b10561b, which includes your fix mentioned above. Upgrade completed successfully - closing this issue. Thanks for the quick fix.
