weird urls…

Hello,
when the plugin is activated and you make a typo.. e.g. “URL/sda”
then you become something like this:

“jqlb_overlay_opacity”:”80″,”jqlb_overlay_color”:”#000000″,”jqlb_overlay_close”:”1″,”jqlb_border_width”:”10″,”jqlb_border_color”:”#ffffff”,”jqlb_border_radius”:”0″,”jqlb_image_info_background_transparency”:”100″,”jqlb_image_info_bg_color”:”#ffffff”,”jqlb_image_info_text_color”:”#000000″,”jqlb_image_info_text_fontsize”:”10″,”jqlb_show_text_for_image”:”1″,”jqlb_next_image_title”:”next image”,”jqlb_previous_image_title”:”previous image”,”jqlb_next_button_image”:”http:\/\/xxx.xxx.xx\/wp-content\/plugins\/wp-lightbox-2\/styles\/images\/next.gif”,”jqlb_previous_button_image”:”http:\/\/test.3sixty5.at\/wp-content\/plugins\/wp-lightbox-2\/styles\/images\/prev.gif”,”jqlb_maximum_width”:””,”jqlb_maximum_height”:””,”jqlb_show_close_button”:”1″,”jqlb_close_image_title”:”close image gallery”,”jqlb_close_image_max_heght”:”22″,”jqlb_image_for_close_lightbox”:”http:\/\/xxx.xxx.xx\/wp-content\/plugins\/wp-lightbox-2\/styles\/images\/closelabel.gif”,”jqlb_keyboard_navigation”:”1″,”jqlb_popup_size_fix”:”0″}; /* ]]> */

if you change this e.g. to “URL/sa”

“jqlb_close_image_title”:”close image gallery”,”jqlb_close_image_max_heght”:”22″,”jqlb_image_for_close_lightbox”:”http:\/\/xxx.xxx.xx\/wp-content\/plugins\/wp-lightbox-2\/styles\/images\/closelabel.gif”,”jqlb_keyboard_navigation”:”1″,”jqlb_popup_size_fix”:”0″}; /* ]]> */

How can this be solved?
Any hints?
thx
