php - CakePHP: Getting a blank page when renaming the folder -

-

i working on cakephp project locally when i'm uploading remote server upload "projectname-new". , after doing tests renamed "projectname" , after renaming original "projectname" "projcetname-old".

however after renaming new 1 "projectname-new" "projectname" i'm getting blank page. when rename or rename other name "projectname" can view properly, when rename "projectname-old" "projectname" can view project properly.

i thought might .htaccess there's nothing weird in file. ideas why might happening?

blank page means either don't have debug @ 1 or more (see "debugging" in cakephp book) or have space or whitespace after closing ?> tag @ end of 1 of files.
