Error function _load_textdomain_just_in_time was called incorrectly

This message gets logged in wp_debug.log (at every request) (see also e.g. at https://plugintests.com/plugins/wporg/tablesome/latest) and seems to originate from your plugin.

Could you please correct the code by moving it to a hook that gets fired later on in the process?

Thanks for your work,

Erwin
