Hello,
Yes, it supports WMPL but our plugin is translation ready you can also translate the plugin through the following methods:
You can translate your job board desired strings, you can do this using POEDIT software. You just have to follow the below instructions.
Using POEDIT, you just have to create the .po file, add the lang_code with the file name and add the strings with their translation like simple-job-board-lang_code.po and place the file in plugin languages directory. After adding strings with translation compile the .po file with POEDIT, it will generate .mo file.
Note: If simple-job-board-lang_code.po file already created then just add the strings with their translation and compile it with POEDIT.
You can also add strings with their translation at GlotPress.
GlotPress Team validates the translation, after validation, it will be updated on GlotPress and you can get translation via WordPress updates.
