Warning about Server Locale (fast fix in my case)

[OLSA]

Hello for all,

also had problem with this warning, and read this and this and find why that's added in PW.

My problem was that I don't have CPanel permissions (only to login to website admin/backend).
Website is multilanguage (3 languages, Montenegro, English and Russian) and try few options for all languages, but always after logout/login get warning message.

There is little confused note: "Default is 'C'. Specify '0' to skip the setlocale() call (and carry on system default)."
I try with "0" to all, but that don't solve problem. Also not sure about "C", maybe need to change note to this: "Specify 'C.UTF-8', or '0' to skip the setlocale() call (and carry on system default)."

Because webiste is hosted on one of the popular european hosting providers, I assumed that there is probably set_locale supported/installed for languages like English, and Russian, but not sure about Montenegro, and try this:

Montenegro: C.UTF-8
English: en_US.UTF-8
Russian: ru_RU.UTF-8

And that fix problem.

Regards.
