In the past I never ever had a issue with Zenphoto ... my server does NOT support 311, 0600 and other permissions that Zenpoto security conscious setup wants to add and their needs to be a option to turn it off because it tool me SEVERAL HOURS to do chmod by hand over several directories just to get my system to normal.
Most Directories were change to "311" and some files were some changed to "00" or "000".
Then the setup log would go over 2 gb in size with errors like ..
WARNING: opendir(/home1/??????/public_html/???????.com/signature/themes/default
----------------------and
/home1/glamwor2/public_html/philbertphotos.com/signature/zp-core/setup/setup-functions.php on line 31
opendir called from getResidentZPFiles (setup-functions.php [31])
from getResidentZPFiles (setup-functions.php [37])
------------------------------
To by pass this and install Zenphoto after changing all the files. was to HACK out the file permission stuff to it would ignore or bypass it ... was NOT a happy time for me.
