strange problem
I have two translation files as you know
theme.mo file and theme.po . file
Everything works
But if you want to translate some words again
I save a lot of translation data
After some effort, I found out before saving that the theme.mo file was too big
1 MB and the theme.po file is 500 KB
If you save the file after translating, all files become 500KB

The problem is that the theme.mo file is not editable
Is there a way to edit it?

I don't know what is the cause of the problem

thank you

.mo file is created based on .po file when translating via PO editor.
.mo file is not editable.

thanks for your reply
But I lost a lot of translation
Is there a solution to recover the deleted translation?
thank you

Do not think so, always use PO Editor

Always use poedit editor
The cause of the problem may be plugin Easy Translator
I think I installed it and it didn't work
Then I removed it
I didn't realize if it was the reason or not

But I hope to find a solution to this problem

Thank you very much

I found the solution
There are sites to convert the file
Convert Gettext MO files
thank you very much

@7ala
I would say simplest solution is to translate .po using PO Editor
Anyway, thanks for info!
