.mo over written with English only

How did you verify, that only english is contained? Still while subblog xy shows up at english?
Did you configure the language for your subblog at network admin for the site?

Well, as soon as I save the .mo file from CL for any given plugin, all my translations are lost and it only displays in English for that plugin only.

The rest of the site displays in my native languae as set in network admin and for the current user. And when I restore the backed up .mo file for that plugin, everything comes back.

What seems to be wrong?

Which component do you try to translate?
Where can I get it for analysis purpose?
My plugin only creates empty translations, if more than one textdomain is contained and the author loads the wrong one. I have to verify it with the affected component (WP, Theme or Plugin).

It is the following theme:
https://themify.me/themes/shopdock

I have checked and it is using different text domain than what is specified. I can still edit and use this with Poedit but it doesn’t seem to work with you plugin.

Is there anyway to make this work with your plugin if author is not responding to our change request to make it work with your plugin?

Thanks for your help.

Could you provide the Theme for analysis pupose by mail (can be found at my imprint page)?
I would check it and search for a suitable solution.

Please check your email.
