Hospedando o plugin Database Collation Fix em um provedor confiável

A MCO2, além de instalar o WordPress na versão mais atual para seus clientes, fornece o WP SafePress, um mecanismo singular que protege e aumenta a performance do seu site simultaneamente.

Por que a Hospedagem WordPress funciona melhor na MCO2?

A Hospedagem WordPress funciona melhor pois a MCO2 possui servidores otimizados para WordPress. A instalação de WordPress é diferente de uma instalação trivial, pois habilita imediatamente recursos como otimização automática de imagens, proteção da página de login, bloqueio de atividades maliciosas diretamente no firewall, cache avançado e HTTPS ativado por padrão. São plugins que potencializam seu WordPress para a máxima segurança e o máximo desempenho.

Since version 4.2, WordPress has been detecting the MySQL version and if it’s version 5.5.3 or greater, automatically selecting the ‘utf8mb4_unicode_520_ci’ Collation Algorithm. This works well until you need to migrate your database to an older version of MySQL that does not support the utf8mb4 algorithms. Then, you run into the error message: “#1273 – Unknown collation: ‘utf8mb4_unicode_520_ci'” when importing your database.

With the WordPress 5.7 update and WooCommerce 5.1, some users are reporting an error: “SQLSTATE[HY000]: General error: 1267 Illegal mix of collations (utf8mb4_unicode_520_ci,IMPLICIT) and (utf8mb4_unicode_ci,IMPLICIT)”. The Database Collation Fix tool also fixes this issue by changing the collation of all columns in your database to use the same algorithm, removing the “mix” of collations.

Usage Scenarios:

This plugin will work in any WordPress install: local, staging or live.

Alternatively, you can install this as a regular WordPress plugin on any site. Once activated, all of your database tables will be updated to use the more portable Collation Algorithm. If you are migrating your web site, you can install and activate the plugin then perform your database export. Once you have migrated your site, you can deactivate and remove the plugin as it would be no longer needed. If you will be exporting and/or migrating your site repeatedly, such as when using it on a test or staging install, you can leave the plugin active indefinitely and it will continue to monitor and update your database tables automatically, allowing you to perform migrations at any time. This is ideal in situations where you are installing or testing plugins that may create their own database tables, as these tables may be created with the newer Collation Algorithms that are not as portable.

How it Works:

The Database Collation Fix tool converts database tables using ‘utf8mb4_unicode_520_ci’ or ‘utf8_unicode_520_ci’ Collation Algorithms to a more portable ‘utf8mb4_unicode_ci’ collation on a once daily basis. It also modifies any column-specific collation statements, not just the default table collation. This means that you can install this plugin and it will continue to monitor all of your database tables and convert them to the more portable Collation Algorithm automatically.

This tool will convert your database tables and columns to use the ‘utf8mb4_unicode_ci’ Collation Algorithm. This can be modified to any other Collation Algorithm you wish by updating your wp-config.php file and adding or changing the following setting:

define('DB_COLLATE', 'utf8_general_ci');

You can use ‘utf8_general_ci’ or ‘utf8’ or any other Collation Algorithm supported by your database. See https://dev.mysql.com/doc/refman/5.7/en/charset-mysql.html for a full description of MySQL’s Character Set and Collation Algorithm selections.
