Also i dont think you mean defecated (which means poo) i think you mean deprecated - which means no longer supported and old.
May I know what do you mean by MirandaDB?
There is MariaDB who replaces the MySQL, I have MariaDB installed on my server, my Oxwall website is running pretty fast on it.
Do you have this 3 extensions installed on your server?
php-mysql
php-mysqlnd
php-pdo
i have the same problem. I'm running a ubuntu 16.04 with LAMP (MariaDB, PHP7 and Apache2) and i get the error message:
Is this a working solution?
Remove mysql in this line:
php.extensions PDO, mbstring, zip, zlib, ftp, json, dom, gd, mysql;
in the file ow_install/files/requirements.txt and as long as you have your MySQL or MariaDB server set up properly, it will proceed and the software still works.
