I have an Ark server here with Survival Severs, and I have been able to successfully access the FTP to manually update the Game.ini and GameUserSettings.ini directly from the FTP; however, over the last several days I get a white screen with the black text reading 'not enough memory' when trying to access it directly via the FTP IP so that I can update the files using the Wing FTP interface set up for us by Survival Servers. I am able to access the files in read-only by adding ftp:\\, but i cannot edit any files with this interface.
I have found no mention of this issue in the pinned articles.
