Sorry for late reply to this,
I noticed when i try to access in your -> https://www.yourDomain.com/ then it will redirect to -> https://www.yourDomain.com/en/ (English version)
Did you changed something language default to English version? Please advise.
Error language solved, disable plugin joomla language.
Yesterday several plugins install and activate the core language by mistake.
Plugin needed "read more".
Now I see, error: http to upload images
