I am trying to import contacts into our database from a CSV file. I cannot reach the first step of the import process because I never get the input field to enter the filename of the CVS file. I just have a field telling me 2 possibilities (SQL and CSV) but this field is not editable and there is no Explorer Windows opening. Strange because it works fine for Import Activities and there I have the Windows Explorer coming to enter the CVS filename. I use CiviCRM 5.21.0 under WP with a laptop under Chrome, Windows 10... Same problem under Edge or under another workstation. Any help will be much appreciated, thanks
Solved by editing the wp_config.php file by adding
ini_set('error_reporting', E_ALL );
after the define section.
