An error has occured
PermalinkAn unexpected error occurred. '\"en_US\"' is not a valid locale identifier
Edit: I have reinstalled concrete 3 times

I couldn't find the error and plan on cleaning up the sample content and moving forward.
Hope the core team can address the error soon. Sure was quick and easy for new folk installing C5 via Softaculous.
Look at the file /application/config/generated_overrides/concrete.php
In this file, you will likely see a locale parameter that looks as follows:
'locale' => '\\"en_US\\"',
---------
Change this to:
'locale' => 'en_US',
This will fix the issue on install from softalicious
I am from the Softaculous team.
We are checking this and trying to replicate the issue on our test servers.
If you are still facing the issue you can open a support ticket with us so that we can debug the issue and resolve it for you :
https://www.softaculous.com/support/...
'locale' => ' \ \ &_quot en_US\\ &_quot',
the locale string has an extra set of quotes wrapping the value
Yes I got that point but we are unable to replicate this on our dev servers. It looks like some server config is causing the additional quotes. If we get access to one of the servers where the issue exists we can find the exact cause and fix the same.
We were able to replicate this issue.
This is caused when you get an error while trying to install a the script via Softaculous and then you again click on install.
We have fixed this issue and the fix will be available in the next version of Softaculous.
Thank you for reporting this issue.
