Avoid cashing sidebar?

Hi

I use Comet Cashe in several sites together with Autoptimize and is very happy with the pluging. Keep up the great job!

On one site I use the sidebar widget plugin “Custom Facebook Feed” (https://sv.ww.wp.xz.cn/plugins/custom-facebook-feed/)

The plugin checks the Facebook feed every 30 min for updates to add news to the site.

My problem is that the feed in the sidebar do not update when I cashe the site. Do you have any tip how to not cashe this info in the sidebar or maby cleare comet cashe automaticly 2 times a day or someting to make this news feed to work without stop using cashe?

The side is: http://prisonisland.nu/

Thanks for info.
