WP prefix on installation - instructions to be indicated

[valentindu62]

Following a bad experience, changing the database prefix from "wp_" to "SAI" for security.

I found out that this is giving Woocommerce a problem with creating tables in the database.

This problem is solved, but I create this ticket to give the idea during the next Update, to indicate how to change the prefix.

I had put SAI instead of wp_ forgetting the _ and capitalizing, hence the problem I had encountered.
