XF 2.3 Upgrade system and php funcons

[Ricsca]

I'm upgrading a forum from 2.2 to 2.3 and I got the following warning.
What can I do?
Thanks

The following warnings were detected when verifying that your server can run XenForo:

• Your server has disabled a core PHP function <strong>exec</strong> via the disable_functions directive in php.ini. This may cause unexpected problems in XenForo.
• Your server has disabled a core PHP function <strong>popen</strong> via the disable_functions directive in php.ini. This may cause unexpected problems in XenForo.

These will not prevent you from using XenForo, but they should be resolved if possible to ensure optimal functioning. However, you may still continue with the upgrade.

This issues likely existed before with your installation of XenForo 2.2. XenForo made some upgrades to its installation checks for 2.3 to make them more robust to better identify missing php functions and options that could have gone unfound and unreported during previous installations.

I'm pretty sure exec is used for XenForo Media Gallery only, and popen is only used if your are using the the built-in PHP mail function. If you are not using either of these, then having them disabled should not be an issue. It would also explain why you hadn't noticed issues previously on XenForo 2.2.
