you don't have a table prefix on any of your tables.
it is just better to have a prefix for each script or program tables so you can tell them apart.
So, did I accomplish this via a particular option in the installation process? Forgive me for not recalling as this is my first experience with phpBB. Is there a way to put the prefix back? Or is it not material at this point, in your opinion? I wish I knew how I arrived to this so that I do not repeat.
PS: thank you immensely for the perspective and sharing your experience.
