Warning: (Optional) `/sbin/md5` was not found or executable; file hashing for multiple images will be slower. Ignore if not using BSD.
Error: vichan does not have permission to create directories (boards) here. You will need to chmod (or operating system equivalent) appropriately.
Error: You must give vichan permission to create (and write to) the templates/cache directory or performance will be drastically reduced.
Error: You must give vichan permission to write to the tmp/cache directory.
Warning: vichan does not have permission to make changes to inc/secrets.php. To complete the installation, you will be asked to manually copy and paste code into the file instead.
