Change Filesystem Permissions
</div>
<h2>
This tool lets you change the filesystem permissions of files and folders owned
by the webserver.
</h2>
<p>
All files and folders in your Gallery storage folder are owned by the
webserver. If you installed Gallery2 by unpacking a .zip or .tar.gz file, then the
gallery2 folder is probably owned by you which means that you can edit the files
directly. However, if you used the preinstaller then your gallery2 directory is
also owned by the webserver. For more information, see the <b><a
href="http://codex.gallery2.org/Gallery2:Security">Gallery Security Guide</a>.</b>

For some reason, your Gallery data folder might no longer be writeable by Gallery itself

to your webhost to get data folder writeable again.
