[Closed] I'm not able to save the header translations

Sorry, we would need a site snapshot to continue with the troubleshooting. Or can we have your permission to create a snapshot on our own?

We usually recommend the free Plugin “Duplicator” for this purpose.

If you already know how Duplicator works ( https://wordpress.org/plugins/duplicator/),please skip the following steps and just send me the archive file you downloaded.

★ Duplicator Instructions hidden link https://wpml.org/faq/provide-supporters-copy-site/

If the file is too large (more than 400M), please use the Duplicator file filters to remove the cache, the wp-uploads directory, the media, and the archive files.

Send me the link to the archive file (you probably want to use Google Drive, Dropbox, or similar services, as the snapshot file will be quite big).

Your next reply will be private, which means that only you and I will be able to see it and have access to it.

You can paste the link to the file there.

Once the problem is resolved I will delete the local site.

Thanks for your reply.

I'm able to duplicate your Website and I'm investigating this and will come back to you as quickly as possible.

Thanks for your patience.

I've received feedback from our 2nd Tier Support and this is what he says.

The site is installed in a subfolder.
Perhaps the rewrite rules are not correct and they might have to be adjusted to accommodate the subfolder.

If you're not sure how to adjust the rewrite rules, maybe you can consult your hosting provider.

Let me know how it goes.

Thanks for your reply.

Glad that you sorted it out. As mentioned by our 2nd Tier Support, the "rewrite rules" needs to be adjusted, so, it's best that you check with your hosting provider.
