HAIF Posted August 21, 2022 Share Posted August 21, 2022 Today I tried to upgrade my form to 4.7, and got almost to the end when it gave me the error CANNOT_WRITE .../system/File/FileSystem.php:337 The file in question, and its parent directories all have the same permissions as before, and the installation made it most of the way through before throwing the error. Both "Retry" and "Continue" just loop back to the same error message. I don't see that anyone else in this forum has had a similar problem, so I'm posting this here to see if anyone has any ideas.

teraßyte Posted August 21, 2022 Share Posted August 21, 2022 (edited) Some servers return errors with 777 permissions. Try using 644. Also I see the file owner is root, is it possible the other files are actually owned by a different user/group? A chmod might work as well.

Marc Posted August 22, 2022 Share Posted August 22, 2022 Usually the above will be related to suPHP/suExec if it needs different permissions than 777. Only your hosting company can answer the question for certain Link to comment Share on other sites More sharing options...
Solution HAIF Posted September 4, 2022 Author Solution Share Posted September 4, 2022 No hosting company here. Just a plain Ubuntu 20.04 server. I found the solution: Change the owner and group of everything in the forum subdirectory to www-data. sudo chown -R www-data:www-data Link to comment Share on other sites More sharing options...
