Please help… I accidentally unchecked all the permissions on 2 of my files. Now I cannot do anything to that file. How can I fix that? I don’t have any backup of that files 
the files that got unchecked are
/functions/acc_mngr.php and
/functions/test_upload.php
Greetings,
Please head over to cPanel >> Manage Website >> Settings >> General then hit on the Repair button; this will fix file permissions
