This occurs when the module installation procedure ends unexpectedly due to missing server / PHP requirements.
In most cases, the specific error is displayed on the screen, but sometimes this generic error may be shown instead.

Here’s what to check on the PHP side (if necessary, with the support of your hosting or system administrator):

• upload_max_filesize should be set to more than 2 MB (we recommend 4 MB or more)
• allow_url_fopen must be active in PHP (you can check this in the Backoffice under Advanced Parameters > Information in the “Check your configuration” tab)
• The PHP extensions XmlReader and ZipArchive must be active
• The PHP version in use must be compatible with the installed Prestashop version – Here you can find the comparison table for Prestashop 1.7 and Prestashop 8

If this checklist turns out to be OK, but the error persists, please investigate your server’s error_log or repeat the installation activating Prestashop’s debug mode (from Advanced Parameters > Performance to try to get a more comprehensive error message).
