Have xoopsgallery installed. Also got installed ImageMagick. Check if it work - xoopsgallery did own checks, responce with "OK".
Click on Gallery-link in main menu, got an "no albums, no photos" - ok, looks good. Then i click on "new album"-link,
page reloaded, but remains the same (no albums, no photos) AND at the bottom i got such notices:
-------------------

Notice [PHP]: Undefined property: app in file modules/xoopsgallery/config.php line 5
Notice [PHP]: Use of undefined constant no - assumed 'no' in file modules/xoopsgallery/config.php line 36
Notice [PHP]: Undefined index: showOwners in file modules/xoopsgallery/config.php line 59
Notice [PHP]: Undefined index: HTTPS in file modules/xoopsgallery/init.php line 74
Notice [PHP]: Undefined variable: GALLERY_NO_SESSIONS in file modules/xoopsgallery/init.php line 107

Notice [PHP]: Undefined property: albumListPage in file modules/xoopsgallery/albums.php line 42
Notice [PHP]: Undefined variable: imageDir in file modules/xoopsgallery/albums.php line 52

--------------
Just to be sure it not becasuse of broken files i checked few notices i got here - looked in files at those strings. There is app-object and there is <no>-without quotes. Can't go deeper in php-code as i'm sure if it works at so many computers, there is no reason to think about if coded right.
So i assumed may be something wrong with my php.
Reinstall it to latest 4.3.6. Still same problem.
Anybody have any ideas?

xoops 2.0.6
xoopsgallery 1.3.3

P.S. All standart modules work ok here - polls, forums, news, agenda-x and few others. What so special about xoopsgallery?
