I wish to replace some files in my "lib" directory (see https://github.com/splitbrain/dokuwiki-plugin-dw2pdf/issues/373
Problem is that each time that I try to suppress, replace, modify the name of the "lib" folder or any of its folder/file I receive a "550 error permission denied".
I have contacted the server administrator. With his admin account he can do it, but not me. He changed the permissions of this folder and content to 777, but still the same error.
I asked him to erase the existing "lib" folder and uploaded a new "lib" folder named "lib_new" in the Dokuwiki main folder. When I try to rename it to "lib" I receive the 550 error. Whereas if I change it to any other name, it will work.
I can install and update plugins from the dokuwiki administrator console
Any ideas ? Thanks in advance.
