FAP SUPPORT - Invalid Combination Of Category Id And Authentication Data
-----------------------------------
When you look (as a normal user, so not an admin) to a personal album that has not yet been created you will see an error with: [quote][color=#ff0000]Invalid combination of category id and authentication data[/color][/quote]

I have fixed it this way:

OPEN[code]/album_mod/album_personal.php[/code]

FIND[code]if ( album_check_permission($auth_data, ALBUM_AUTH_UPLOAD) == true )
			{
				$template->assign_block_vars('index_pics_block.no_pics.manage_personal_gal_folders', array());
			}[/code]

REPLACE WITH[code]if ( album_check_permission($auth_data, ALBUM_AUTH_UPLOAD) == true )
			{
				$template->assign_block_vars('index_pics_block.no_pics.manage_personal_gal_folders', array());
			}
			else
			{
				message_die(GENERAL_MESSAGE, sprintf($lang['Personal_gallery_not_created'], $username));
			}[/code]

I don't know if it's good, but it works.  :P
