Support

Your server must meet the minimum PHP version noted in the setting's name.

Please note that it is possible that your server has more than one PHP versions installed at the same time. The PHP version your site is being run under may not be the latest PHP version available, and it may also not be the PHP version in your hosting control panel. Especially regarding the latter, please keep in mind that what is reported is the PHP version the hosting control panel runs under, NOT the PHP version your site runs under – in fact, the latter is not something that can be reported as it is technically possible to have a different PHP version handling different PHP scripts or directories on your site.

If you receive an error here it can never be a bug. It is PHP checking its own version, hardcoded into the PHP executable itself when it was compiled and installed on your server, against the version number printed in the message. You need to contact your host and ask them how you can select the PHP version for your site.

Important

In many cases your host will tell you to modify your site's .htaccess file, or use a tool in the hosting control panel which does the same. Since the .htaccess file may be overwritten later during the restoration process you may have to apply the PHP version again after the Site Setup step of the restoration. You can avoid this rigmarole by choosing the PHP version before extracting the backup archive. BRS will see the relevant lines in the .htaccess and propose to transcribe them for you.

The PHP version currently used to run your site must have the mysqli extension installed and enabled. Moreover, the various mysqli_* functions must NOT be disabled in PHP's configuration.

Kindly note that an error here can never be a bug. BRS simply asks PHP to tell it if the functions used to connect to a MySQL database using PHP's mysqli extension are available. An error means that PHP itself reports it will not be able to connect to the database.

If you get an error here, please ask your host how to enable the mysqli extension. If you are unsure which PHP version is being used, scroll down to the Site Information section of the page and look at the PHP version line. The version currently used on your server is shown under the Current column.

	Important
	PHP offers two ways to connect to PHP databases: the mysqli extension, and the MySQL PDO driver (the pdo_mysql extension). WordPress only supports the mysqli extension.

The PHP version currently used to run your site must have the json extension installed and enabled. Moreover, the various json_* functions must NOT be disabled in PHP's configuration.

Just like with database support, an error here can never be a bug for similar reasons. If you get an error here, contact your host.

The PHP version currently used to run your site must have the zlib extension installed and enabled. Moreover, the gzcompress function and the other related Zlib functions must NOT be disabled in PHP's configuration.

Just like with database support, an error here can never be a bug for similar reasons. If you get an error here, contact your host.

Different WordPress versions have a different PHP maximum version supported. If you use a PHP version which is "too new" for your WordPress version you may end up with PHP notices, or warnings. The presence of these messages might leak security-sensitive information, or may break your site e.g. make it impossible to log in, or use some core WordPress and/or plugin features. This is especially problematic if Display Errors below is shown as not being in the recommended value.

The display_errors setting in PHP's configuration must be set to 0, preventing the output of PHP notices, warnings, and errors to the browser. The presence of these messages might leak security-sensitive information, or may break your site e.g. make it impossible to log in, or use some core WordPress and/or plugin features.

Your PHP version must be configured to support file uploads for some features to work such as managing media files, or installing plugins outside of the WordPress Plugins Directory. If you see an error here it's best to contact your host.

The version of WordPress, as detected by BRS.

The domain name of the backed up site, and the one you are restoring to. If the domain name or subdomain is different you will have to go through the Replace Data page for your site to work properly.

Then the backup was taken on, and when it's being restored. It is a good idea to always check the date of the backup you are restoring, and make sure it is indeed the backup you meant to restore.

The value shown "At Backup Time" is the version of Akeeba Backup for WordPress or Akeeba Solo you used to take the backup. The "Current" version is the version of BRS which is different than the version number of the backup software.

The PHP version used when backing up the site, and the PHP version being used during the restoration.

The absolute filesystem path of the site's root folder. If it is different at restoration time you will have to go through the Replace Data page for your site to work properly.
