FAQ

I get the message: “[fgoc2wc] Couldn’t connect to the OpenCart database. Please check your parameters. And be sure the WordPress server can access the OpenCart database. SQLSTATE[28000] [1045] Access denied for user ‘xxx’@’localhost’ (using password: YES)”

  • First verify your login and password to your OpenCart database.
  • If OpenCart and WordPress are not installed on the same host, you can do this:
  • export the OpenCart database to a SQL file (with phpMyAdmin for example)
  • import this SQL file on the same database as WordPress
  • run the migration by using WordPress database credentials (host, user, password, database) instead of the OpenCart ones in the plugin settings.

The import is not complete

  • You can run the migration again and it will continue where it left off.
  • You can add: define('WP_MEMORY_LIMIT', '2G'); in your wp-config.php file to increase the memory allowed by WordPress
  • You can also increase the memory limit in php.ini if you have write access to this file (ie: memory_limit = 2G).

The images aren’t being imported

  • Please check the URL field. It must contain the URL of the OpenCart home page

Are the product attributes and options imported?
