Hi I started getting this error:

Fatal error: Cannot use string offset as an array in ../sapphire/core/i18n.php on line 1417
Sounds like a translation thing
I am using 2.3.3

I can access nor main site neither admin.

Any ideas to resolve the issue is appreciated.

Thanks in advance

Definitely is, something has hosed the SS global $lang. Are you setting it elsewhere, and have you checked that your translations files are intact?

Thanks for replying,
I am setting it in the _config file as
i18n::set_locale('tr_TR');
i18n::set_default_lang('tr_TR');

The interesting part is that everything works fine on my local machine but the same files do not work when
I upload it to my hosting account.

I even tried installing from scratch on my hosting account
and even the install hangs with the same error.Weird...

When I change the line in i18n.php on line 1417 from
$transEntity = isset($lang[$locale][$class][$realEntity]) ? $lang[$locale][$class][$realEntity] : $string;
to
$transEntity =$string

I can access the site but then translations do not work anymore.

Bump...

The problem is resolved.

I just had the same problem, my locale was set to en_NZ. it has been working for a few weeks, and suddenly i was getting these php errors.

changing to US fixed it on the public site, but the admin didn't work at all.
after a while of frustration, I tried using firefox instead of chrome. and it worked prefectly.
i shut down chrome, reopened- and, yes, all working

so if you experience this problem and it's just started, try closing and reopening....
