Hello,
I would like to update my platform and plugins through the backend but I work locally with wamp and I don't know what kind of ftp access I'm supposed to enter. Any idea?
you can just update them manually: https://docs.oxwall.org/install:update
read this post: http://www.ozzu.com/hosting-forum/chmod-with-apache-windows-t25108.html
Alright, can you login to your local server via FTP?
what are the permissions of ow_static folder you see there?
if it's not 777 change it to 777.
Do the same for ow_userfiles, ow_pluginfiles, ow_smarty/template_c
You need to set the permissions 777 recursively.
However as far as I know CHMOD is not supported on Windows OS's, only Linux/Unix systems.
