Undefined index: use_pager on line 108 in plugins/cache/simple.inc

I solved my problem by just disabling cache for each panel

I solved my problem by just disabling cache for each panel i.e.
in the panel contents tab change caching (Caching->change=> No Caching) for each panel by clicking on the settings anchor at top-right of each panel.

(Note: I was using 7.x-3.x-alpha2 but the message was the same)

Removing tags for duplicating the "Assigned" or "Component" fields.

I have this problem also ...
Let me share possible solution for this problem;

- Open file "plugins/cache/simple.inc" which is located in panels module folder,
- Find line 108;

if($pane->configuration['use_pager'] == 1) {

- Replace line 108 with the code below;

if(isset($pane->configuration['use_pager']) && $pane->configuration['use_pager'] == 1) {

I hope it works ...
It should be ...

Fixed the notice.

Here is a patch for Drupal 6. It was even in a same line so I guess it fits to D7 too, but I haven't tested.

Works for me.

This is an alternative patch that changes that line to use the same code as the D7 version; I've also included a D7 patch to fix the formatting of that line.

Looks good.

Fixed in d6. Need to bring into D7.

This was already committed to the 7.x-3.x branch.
