I tried out the plugin that you mentioned. https://wordpress.org/plugins/loco-translate/
In Alora theme, it comes only with the en_US.po and en_US.mo
You can use this plugin to create the po and mo files of the languages that you need and then start translating the theme’s strings.
After you install the plugin, you can go to the plugin’s setting page and click on “New Language”
Please see screenshot http://prntscr.com/7db3r8.
Then you can select the language you want and the plugin will create a new po file for that language and it will load the strings into it for you to translate.
Please see screenshot. http://prntscr.com/7db46n
Hope it helps.
Sorry, that’s all we can provide for a third party plugin.
