Blank screen and copyright info. -

I have a new install on aws server. Everything was working fine until last night when suddenly I got the blank screen with copyright info. My error is as follows:

Any ideas?

Hi,
please open config.php file from /data/ directory and check how the 'tabList' is represented. If it looks like:

'tabList' => ['Account', 'Contact', 'Lead', ...]

I is wrong. It should look like:

'tabList' => [
    0 => 'Account',
    1 => 'Contact',
    2 => 'Lead',
    3 => 'Opportunity',
        ....
]

Please describe what did you do when the blank page occurred?
