This thread is resolved. Here is a description of the problem and solution.
Problem: We are getting tons of error on our website and not sure how to fix them: PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function WPML_Archives_Query::get_archives_join
Solution: I just had a look at the error message and I could see that this issue is related to the Better archives widget plugin. Once you deactivate it, everything should go back to normal.
