Issue trying to upgrade

[Guest]

Hello,

I'm trying to upgrade my current vb version to 5.1.5


Error:
Unexpected Text:
<?xml version="1.0" encoding="UTF-8"?>
Warning: Invalid argument supplied for foreach() in .../install/includes/class_upgrade_515a3.php on line 82
<upgrade>
<message replace="0">Updating navbar link for New Topics.</message>

</upgrade>

Upgrading to 5.1.5
Status: Aborted

Upgrade Progress
Upgrading to 5.1.5 Alpha 1
Step 1 - Altering privatemessage Table (1 of 1)
Upgrading to 5.1.5 Alpha 2
Step 1 - Altering channel Table (1 of 1)

Then I tried by runing again the upgrade process and it shows another error in the last step:

Another error during the upgrade: Unexpected Text:
<?xml version="1.0" encoding="UTF-8"?>


What should I do? If I'm missing any files where should I put and which version?

Thank you very much!

I fixed this via the ticket.

Upgrades stuck at the very end (step 19 of 19) - log into the AdminCP and import the master style out the download package (core/install/vbulletin-style.xml).
It can take several minutes on large sites.
When it's imported, re-run the upgrade script and it should complete pretty much immediately.

Just another question, the first error I received during the installation in the first line is related to this?
