Description

Hi,

I am having a problem with cosmetic filters on some pages of my internal nextcloud server. The sharing tab is empty in some cases.

When I disable the cosmetic filters, it is working as expected. This problem was reported in the respectiv nextcloud app before: nextcloud/polls#4234

Thanks for your work, you are a life saver.

• I did not enable additional filter lists, or I have verified that the issue still occurs without enabling additional filter lists.

Caused by EasyList – Social Widgets list. Add this as your custom filter:

yourdomain.com#@#.sidebar-share

or turn off that list, or report to https://github.com/easylist/easylist/issues/
