 * Hi,
 * I have an issue with the configuration of Dynamic Widgets;
 * when i want to define the pages where the widget should appear i see at the bottom
   of the listed pages following message:
 * Notice: Undefined variable: widget_id in /xxx/xxx/xxx/xxx/xxx/wp-content/plugins/
   dynamic-widgets/mods/pages_module.php on line 123
 * If i try to apply the settings it throws me following messages on top of teh 
   backend:
 * Notice: Undefined offset: -1 in /xxx/xxx/xxx/xxx/xxx/wp-includes/rewrite.php 
   on line 376
 * Notice: Undefined offset: -1 in /xxx/xxx/xxx/xxx/xxx/wp-includes/rewrite.php 
   on line 378
 * Warning: Cannot modify header information – headers already sent by (output started
   at /xxx/xxx/xxx/xxx/xxx/wp-includes/rewrite.php:376) in /xxx/xxx/xxx/xxx/xxx/
   wp-admin/includes/misc.php on line 1116
 * Any ideas where that comes from or how to fix it? For information, i have applied
   permission settings on files 644, folders 755 for safety.
 * Thanks in advance & best regards
 * Startx04

 * You’ve probably dragged a widget into a sidebar and then immediately edit the
   Dynamic Widgets settings. Please save the widget first before you do that.

 * Hi Qurl,
 * Thanks for the quick response. Usual i save before moving on, and i tried again
   to make sure i did. No changes, same errors.
 * I there is an incompatibility with the [“Tag Pages”](https://wordpress.org/plugins/tag-pages/)
   plugin and the WPML plugin, maybe in combination with the Enfold Theme from Kriesi.
 * I can workaround that, but having script errors all the time doesn’t make me 
   comfortable to use it as a production environment.

 * Hi [@startx04](https://wordpress.org/support/users/startx04/),
 * As far as I know there are no compatibility issues with WPML and Tag Pages. If
   you do encounter issues with Tag Pages, just let me know via the Tag Pages forum(
   [https://wordpress.org/plugins/tag-pages/](https://wordpress.org/plugins/tag-pages/))
 * All the best,
    BjornW (Tag Pages’ author)

 * It might be the widget you’re using which have an incompatibility. You can try
   to use one of the standard widgets that come with a vanilla WP install and see
   if the problem persists.
