Plesk for Windows Plesk for Linux kb: technical ext: wptk

Applicable to:

  • Plesk for Linux
  • Plesk for Windows

Symptoms

  • The WordPress Instance is marked as broken in Domains > example.com > WordPress after migration using Site Import extension from Windows to Linux server:

    PLESK_INFO: Broken WordPress installation
    WP Toolkit has found WordPress files at the following path:

    /var/www/vhosts/example.com/httpdocs

    However, it does not seem that this WordPress website is working. Try restoring the website from a backup or cleaning up the redundant files. 

  • Error details is showing the following message:

    PLESK_INFO: Error: The site you have requested is not installed. Your table prefix is 'ABCdfg_'. Found installation with table prefix: abcdfg_. Or, run `wp core install` to create database tables.

Cause

Case sensitivity of the created database table prefix.

The tables are presented on both servers, the actual prefixes on both servers are abcdfg_.
$table_prefixspecified in wp-config.php is ABCdfg_ on both servers.
The instance is working correctly on the Windows server with these settings, but not on the Linux server after migration.

Resolution

Change the $table_prefix to the actual table prefix of the tables abcdfg_ in the wp-config.php file:

  1. Log in to Plesk.

  2. Go to Domains > example.com > WordPress > root directory and open the wp-config.php file.

  3. Change $table_prefix to actual tables prefix and save the changes:

    CONFIG_TEXT: $table_prefix = 'abcdfg_';

  4. Go to Domains > example.com > WordPress tab > Open WP Toolkit and refresh the instance:

    Me too, same issue.  Table prefix was correct but still I get Broken Installation.  I removed and re-attached the site but no luck. All plugins, WP core and themes are up to date.
