Nikolai Shcherbin Thank you, the problem is solved

I don't think that but if you want...:

'routes' => [
      'account:register' => [
          'path' => '/here-is-my-new-register-link',
          'resource' => 'account/register',
          'walled' => false,
          'middleware' => [
             \Elgg\Router\Middleware\LoggedOutGatekeeper::class,
          ],
     ],
],

In elgg-plugin.php of your custom plugin.

I do not see System Log plugin in my installation

Nice.

I do not understand.

Ahh. Elgg 2.x.

Sorry, you haven't such option ¯\_(ツ)_/¯

It's time to upgrade.

It will take me sometime to upgrade. I have continue with the 2.3.

I think I saw a discussion about the same topic with a suggestion how to do it on 2.3 but I cannot find it right now.

If MariaDB is used on your sever you need to adjust two things to get Elgg fully working. Unfortunately, I can only tell you how I had to adjust the configuration on my (local) Linux installation to get it working. The server configuration might be different in your case depending on what tools are available for server administration and where the necessary config files are to be found. If you don't find out yourself how to alter the DB server config, ask the support of your wehboster.

Firstly, the "archive" database engine needs to be enabled. In case of my server the file is in /etc/my.cnf.d/default_plugins.cnf:

[server]
plugin-load-add=archive=ha_archive.so

The second change I had to do was in /etc/my.cnf:

[mysqld]
max_delayed_threads = 0

I've only posted the relevant lines and the sections these lines would be in the config files. So, there could be other content in these files you wouldn't have to modify.

The archive engine is necessary for the log table rotation to work, i.e. older log entries are moved into a new table. If you don't need the log entries in the database, you can also use this plugin: https://elgg.org/plugins/1441338. Then the entries won't be created in the first place (on Elgg 3 or newer you could disable the corresponding plugin for the same effect). And you can increase the log rotation interval in the plugin settings.

The delayed thread settings in my.cnf is necessary for an issue I also had regularly with MariaDB. I don't remember at the moment what action caused it (I had opened an issue in the Elgg repository at github but then realized how to "fix" it by adjusting the DB server configuration). The delayed queries happen only rarely, sothe delayed thread setting shouldn't decrease performance at all.
