Hello 
I changed the file config.php. I wanted to add a domain to this file.
Unfortunately, I did not back up the file. After this change, I tried to restore the previous options.
I added the server name again Unfortunately I do not remember the whole array code.
Unfortunately, all the shared files have a message Unspecified share exception
Please advice, unfortunately my knowledge about servers and owncloud is small.
sorry for my English
