I need Easy Appointments in Russian, but it wasn't on the language list. I made the translation myself by creating localization files named easy-appointments-ru_RU.po and easy-appointments-ru_RU.mo in Poedit, and uploaded these files to the folder ../wp-content/plugins/easy-appointments/languages.
The only thing left is to switch the program language from English to Russian, but I can't figure out how to do it. There is no option to select the localization language in the program settings. I'm asking for your help.
