Find your XenForo, PHP and MySQL versions
Three version numbers decide which add-ons you can run. Here is where to find each one, and what XenForo 2.2 and 2.3 need.

Three version numbers decide which add-ons you can run: your XenForo version, your PHP version and your MySQL version. XenForo shows all three in the Admin CP, so there is no need to ask your host. They are also the first three things we ask for in a support ticket.
Your XenForo version
Look at the bottom of any Admin CP page. The footer shows the version next to the copyright line, for example v2.3.13. The first two numbers are the ones that matter for add-ons: a forum on 2.3.13 is a XenForo 2.3 forum.
Each D.C Style product page lists what the add-on needs under Compatibility, for example "Needs XenForo 2.3.0+". Reading version numbers explains what that means for older forums.
Your PHP and MySQL versions
Open the Admin CP home page and scroll to the Server environment report. It lists:
- PHP version, the version your forum actually runs on
- MySQL version, the database server version
- Server software, and whether PHP extensions such as Imagick and ZipArchive are available
The report only appears for administrators who have the "View server information" permission. If you cannot see it, ask the forum owner or check Groups & permissions > Administrators.
If your PHP version is older than XenForo recommends, the report says so in a warning. XenForo 2.3.13 recommends PHP 8.3.
Tip: Running
php -vover SSH shows the command-line PHP, which is not always the same version your website uses. Many hosts run several PHP versions side by side. When an add-on needs a certain PHP version, trust the Server environment report.
What XenForo 2.3 needs
XenForo 2.3 will not install or upgrade on anything older than:
- PHP 7.2.0
- MySQL 5.7
Those are the minimums. Some add-ons need a newer PHP than XenForo itself, as the table below shows.
What D.C Style add-ons need
Most of our add-ons run on any PHP version XenForo supports. These ones need more:
| Add-on | Needs |
|---|---|
| Google Drive Attachments | PHP 8.1 or newer. The Google libraries it bundles will not run on older PHP. |
| Login As User | XenForo 2.3.0+ and PHP 8.0 or newer |
| Forum Statistics | PHP 8.0 or newer |
If an add-on's PHP requirement is not met, XenForo usually refuses to install it and names the requirement. An add-on that loads extra libraries can instead stop the whole site with an error. Site down after installing an add-on? shows how to recover.
Your add-on versions
Every installed add-on is listed on the Add-ons page with its version next to its name, for example "1.0.7". Over SSH, php cmd.php xf:addon-list prints the same list. More command-line tools.
Still stuck? Open a support ticket and include your XenForo, PHP and add-on versions from the pages above. With those three numbers we can usually tell you right away whether an add-on will run on your forum.
