It's not possible to edit files from the cPanel File Manager anymore, at least not when logged in via https. This error is shown:
"Internal Server Error
Can't locate auto/Net/SSLeay/ssl_read_al.al in @INC (@INC contains: [long list...] .) at /usr/lib/perl5/site_perl/5.6.2/IO/Socket/SSL.pm line 610"
Creating folders or files also fails.
