I purchased a second license for PG after checking with Jason exactly what to do with my server set up and all is good. I do think Safari cache has an issue, but if using another browser for editing in the system, all is good. So this is what I did to make for my particular server, per Jason's patience.
On some servers the permissions for the gallery and webassist folders and
all files and folders underneath need to be set to 755, and the
webassist/caching/PG_CachedResize_Image.php file needs to be updated to
change line 14:
$retVal = is_dir($pathname) || @mkdir($pathname, 0777);
to:
$retVal = is_dir($pathname) || @mkdir($pathname, 0755);
and line 360:
mkdir ($cachefolder,0777,true);
to:
mkdir ($cachefolder,0755,true);
And the admin_gallery/common/properties.php file needs to be edited to
change:
$GLOBALS['permissions'] = array(
'dir' => 0777,
'file' => 0666
);
To:
$GLOBALS['permissions'] = array(
'dir' => 0755,
'file' => 0755
);
Thank you Jason for explaining it for me so I can address. Very much appreciated.
