This info is for those who may face the issue.
After installing v4.4.9, the Adminer throws an error when we fill the user and password and then click Login.
The error is in file /app/adminer/adminer.php.
The line is like return(min_adminer_version("5.5.3",0,$g)?"utf8mb4":"utf8");
The message is about function min_adminer_version that doesn't exist.
We changed it to return "utf8mb4" unconditionally and now the Adminer works.
Thanks.
