I am trying to upgrade.

Apache Version 2.2.26
PHP Version 5.3.26
MySQL Version 5.5.42-cll

Warning: require_once(/home/cppc/public_html/foro/includes/vb5/../../config.php) [function.require-once]: failed to open stream: No such file or directory in /home/cppc/public_html/foro/includes/vb5/config.php on line 44

Redo your config files, refer to post #3.

Thank you. I deleted everything and now I am uploading the files again. I am confused about the instructions, here is my explanation:

Instructions by vbulletin:
----------------------------
After uploading the files to your chosen location on your server, open your web browser and enter in the address followed by your vbulletin_root and install/upgrade.php.
Example: http://www.example.com/forums/upgrade.php
--------------------------

As per the first paragraph I am being instructed to point by browser to: www.domain.com/install/upgrade.php

However, the example is instructing me to point my browser to www.domain.com/upgrade.php

Which one is correct or are they both correct?

if you have your folders in a forum folder then it would be
http://www.example.com/forums/install/upgrade.php (http://www.example.com/forums/upgrade.php)
if not in a forum folder then it would be
http://www.example.com/install/upgrade.php (http://www.example.com/forums/upgrade.php)

If you are installting 5.1.5, then you need to upgrade your PHP to PHP5.4.

PHP Minimum Version
Due to changes in required third-party libraries, the minimum required version of vBulletin 5.1.5 and higher will be PHP 5.4.0. Also at this time, PHP 5.3.X has reached end of life and will no longer be updated. It is recommended to upgrade your servers to 5.4.0.
