@elio Rivero Thank you for your kind reply..
i already tried all the steps you suggested.
i even set all the file permission to 777
after that i got the 500 internal error on all the pages.
problem i figured out is
Wp backup + better wp security + auto creation of .htaccess in cpanel=
All sott of errors, i’ve deleted the whole wp installation ,
So, marking this as Resolved.
Thank you
