 * Hi guys,
 * i installed the last version of plugin on a 3.0.4 wordpress instance. When i 
   active the plugin i have di error:
 * `Catchable fatal error: Argument 1 passed to UTCW::__construct() must be an instance
   of UTCW_Plugin, boolean given, called in C:\xampp\htdocs\fuu\wp-includes\widgets.
   php on line 77 and defined in C:\xampp\htdocs\fuu\wp-content\plugins\ultimate-
   tag-cloud-widget\utcw-widget.php on line 38`
 * I tried to install it on a 3.0.4 vergin wp instance too. Can someone help me 
   please?
 * Of course no problem with wp 3.5 but a client is stuck on 3.0.4 -.-

 * I just tested this myself and it seems like there’s a problem with older versions
   of WordPress.
 * I’ll try to get to this issue this weekend.

 * Little update.
 * In utcw_widget.php in line 40 i changed:
 * `parent::WP_Widget( false, __( 'Ultimate Tag Cloud', 'utcw' ), $options );`
 * with
 * `parent::__construct( false, __( 'Ultimate Tag Cloud', 'utcw' ), $options );`
 * This is the PHP5 constuct, WP_Widget is for PHP4.
 * Now i’m able to use the plugin BUT when i click on Terms, Basic Appearence, ect
   it doesn’t switch. I have a classic POST-call, it return on “Data” and i’m not
   able to access in the others option page.

 * Hi, thank you for also taking a look at this.
 * To me, this sounds like a PHP version incompatibility. What version of PHP are
   you using?

 * I deleted all `<fieldset>` tag from setting.php
 * Now i’m able to see and use all others option but i have all on the same box 
   ofc.
 * Anycase i think the problem is in javascript and not in php. Does the script (
   utcw.min.js) depend on others script??
 * Tnx.

 * The utcw.js script depends on jquery only, and should be compatible with the 
   jquery version all the way back to 3.0.
 * I’ll try installing old wordpress and see for myself.

 * I tried to load jquery 1.8.3 (it’s in wp 3.5) instead the old version, but it
   doesn’t work.
 * 🙁

   I have had a look.
