Database updating issue during the installation or during the default language changing

It's important to know that some countries have a large databases related their cities or administrative divisions and need high server resources during databases importation.
This is the same for the default language changing when all translatable entries in the database need to be updated.

So you will need to set your server's max_execution_time to bigger value than default 30s before starting the installation or before changing the default language.

NOTE: To avoid your server's the loading time and file size limits issues, we recommend to increase some values of your server like the max_execution_time, post_max_size and upload_max_filesize.

If the issue occurred during the installation, you have to make a fresh installation by removing the "/.env" and the "/storage/installed" files (if exist) before starting again.
