Drupal 7.x

Hello! How are you guys?
I'm working on a project in Drupal and found the following difficulty.

I currently have a menu like this:

And I would like to customize it this way:

However, I do not know in which file is located the links of each section of the menu so that I can go there and insert the icons and then stylize them.

Inside my page.tpl.php file I have a code like this:

​​​​​​​<?php print render($page['horizontal_navigation']); ?>

Since a few months the locales_source table of one of the Drupal sites on my VPS gets corrupted regularly. Until now I just reverted each time using a snapshot to fix, but the table keeps getting corrupted. I am getting annoyed and want to permanently fix this.

This is the error:

xxx is not adjourned anymore. Why? Can I force cron with a command in cpanel?

I have a lot of sources: can be this the problem?

Thanks
