Hi I have just installed a new wordpress site. When I try to log in into the admin section, I het a blank screen (after entering user name and password).
How did you install? Sometimes installing with FTP causing some failed transferred files. I suggest you to install manually without FTP, or try to install once again.
Upload the fresh downloaded wordpress.zip file from wordpress.org site to your cPanel and then install.
Try editing the wp-config.php....... You need to remove the blank space at the end of the file after ?>...........It will solve your problem 80% but still that gives you problem so reinstall it.. You can ask wordpress experts if you stick again....
