After installing the free version of the plugin (both directly from the repository and through a .zip file) on a 6.4 WordPress, I get the following error:
Uncaught Error: Call to undefined function WPStaging\Framework\Adapter\Database\mysql_query() in /home/grupoaidas/apps/displayrapid/wp-content/plugins/wp-staging/Framework/Adapter/Database/MysqlAdapter.php:37 Stack trace: #0 /home/grupoaidas/apps/displayrapid/wp-content/plugins/wp-staging/Framework/BackgroundProcessing/Queue.php(1383): WPStaging\Framework\Adapter\Database\MysqlAdapter->query(‘SHOW COLUMNS FR…’) #1 /home/grupoaidas/apps/displayrapid/wp-content/plugins/wp-staging/Backend/Upgrade/Upgrade.php(89): WPStaging\Framework\BackgroundProcessing\Queue->maybeAddResponseColumnToTable() #2 /home/grupoaidas/apps/displayrapid/wp-content/plugins/wp-staging/Backend/Upgrade/Upgrade.php(72): WPStaging\Backend\Upgrade\Upgrade->upgrade3_0_7() #3 /home/grupoaidas/apps/displayrapid/wp-content/plugins/wp-staging/Backend/Administrator.php(224): WPStaging\Backend\Upgrade\Upgrade->doUpgrade() #4 /home/grupoaidas/apps/displayrapid/wp-includes/class-wp-hook.php(324): WPStaging\Backend\Administrator->upgrade(”) #5 /home/
What can I do to fix it? Thank you in advance.
