Hello, there are a few issues:
– The process of manual translation is very arduous as you have to translate every paragraph, one after the other. You cannot paste translation of whole page at once.
– When you change something in original page (for example punctuation) – the fragment of translation is “detached” and you have to translate it again
– if you set “Force language in custom links” using the plugin “Change wp-admin login” or similar – it makes signing in impossible
– You cannot change the default language easily
That’s why I think that your plugin is usefull only with very simple websites.
Thanks for you reply and best regards!
