Thanks for Sunny giving us a feedback.
The issue description
Hi, i’m using WPvivid with my wordpress site. Everytime I try to backup Database+File (Entire website), it comes to an error saying “wpvivid_request: error (Internal Server Error): an error occurred while preparing the backup. This error could be caused by an unstable internet connection. Please try again later.”
However, if I only backup Files (excluding database), it works.
How do I get rid of this error?
The cause of issue
This error is caused by PHP PDO extension. While backing up entire website including database, It is necessary to enable this extension.
Please run the following command line to enable PHP PDO extension:
Depending on PHP version, please run the command line below:
php5enmod pdo for PHP5 phpenmod pdo for PHP7
Next, depending on your case, you need to restart Apache or Httpd with the following commands :
service apache2 restart for Apache
service httpd restart for Httpd
After running the command lines correctly, Backup WordPress Site by WPvivid will be able to backup your site successfully. However, if you are hosting your site on a shared hosting, you need to contact your web host provider to enable PDO extension.
