4.15 Upgrade Aborting - Cannot Perform Upgrage

[eshrink]

Thank you. I assumed that this is a script problem in vBulletin.

However, I looked at .htaccess and found this:
<IfModule mod_php5.c>
php_value auto_append_file "google_verify.php"
</IfModule>

<IfModule mod_php4.c>
php_value auto_append_file "google_verify.php"
</IfModule>

Am I to assume that my host does not need these files and that they were planted by some malware?

This is interesting. I had already uploaded and overwritten the 4.14 PL2 files, yet the website appears to run fine (as though the upgrade script has never been attempted.
