hello..
i'm jay, i currently learn how to develop website using wordpress.
i really love wordpress with tons of plugin and theme available out there, i just learn how to write my own custom widget.
my widget is work fine when i include it on my theme function. its show on backend and also on frontend just like another widget.
the only problem i got, when i add/create another widgets, the widgets(all widgets) start act wierd. when i add the widget(s) to widget area it show the options(form) but then option suddently dissapear. when i try to refresh the page (widget.php) on admin area the options on that widget appear normal and i can modify the value on that widget and save it just like normal widget.
this behavior affect the other functionality in my admin area such ass add image thumbnail is wierd(i can add thumbnail image, but image not shows on the thumbnail section on editor page.
and also with the other functionality, for example when i add new post it show on blank page when i hit save, also the same condition for adding category, page, menu, or anything that say add new. even on saving my theme options it direct me to blank page after i hit save.
this is the widget code.
