How to remove symlink from folder

Do you have any access to the server? SSH access? If you can get to a command line on the server you could try one of these commands. Using sudo would try and run the command as an administrator, so you would need a password:

unlink /path/to/symlink

sudo unlink /path/to/symlink

rm /path/to/symlink

sudo rm /path/to/symlink
