Installation Error with version 3.5.17

Checked this problem with Microsoft Edge, Firefox and Chrome web browsers and I get the same error in both the main page and back office.

I have installed v3.5.17 via 1&1 control panel, as this is their latest update with a date stamp of 20.09.16, and I am getting errors on the home screen of my website.

Code:

---

Would it be best to over write this installation with up-to-date version, or is there something fundamentally wrong with the initial load?
My site address if you want to take a look.

Edit your /system/config/localconfig.php and change this line

PHP Code:

---

$GLOBALS['TL_CONFIG']['dbDriver'] = 'MySQL';

to

PHP Code:

---

$GLOBALS['TL_CONFIG']['dbDriver'] = 'MySQLi';

e right
My site is now showing the 'we'll be right back' in the middle of the screen.

Thank you for the info.

That's the screen for the maintenance mode. You can disable the maintenance mode in the backend or directly in the /system/config/localconfig.php
