Installed an Update
An unexpected error occurred.
'_' is not a valid locale identifier
Did you install concrete5 using Softaculous? If so, you may want to review the following discussion.
Now I've got the same error (as many users have) and there's no solution for it or downgrade possibility because before the update the site was working fine...
Pls provide a workaround or solution....
Your hint is awesome!!!
Thank you very much!
