Translatepress Plugin Error message

I have a website, robot-store.co.uk, which is aimed solely at a UK audience. However, we have acquired a new website for an international audience called robot-atelier.com. I requested my hosting company to clone robot-store.co.uk to robot-atelier.com so we could initially start with the French language and later add other languages. I have added robot-atelier.com/fr to reach French-speaking audiences, but we received the following message:

“Something went wrong, please try again.” Please see the attached TranslatePress screenshot for better understanding.

Additionally, I would appreciate your suggestions or recommendations on the following:

1. I have set French as my default language instead of English; is this correct?

2. I deactivated the “floating language selection” (see screenshot #2) because I only have French on this website, and more guidance would be appreciated.

3. Should the HTML Lang Attribute Format be set to “Default” or not?

4. I enabled the hreflang x-default tag for languages and added France; please confirm if this is correct. (see screenshot #3)

The plan is to start with French-speaking countries; however, as I am new to Translatepress, I have not yet read all the documentation. I want to ensure that I am using Translatepress correctly, as I do not want my original website, robot-store.co.uk, to be affected by having the same information on robot-atelier.com. My UK website is currently performing well, and I just want to ensure that SEO, duplicate content, and so on, do not negatively impact robot-store.co.uk.

I would appreciate your guidance to ensure I am on the right track. Also, please let me know the reason for the error message “Something went wrong, please try again,” and what actions I should take regarding it. Thank you.
