About "the page is still broken after I created all necessary rules"

It may happen that a page is still broken after force-reloading once you have created all the needed allow rules for it.

Here are some things to consider.

• Did you use the logger to ascertain that really nothing is blocked or modified?
  • Using the logger is the first step when having trouble to un-break a site.
• Did you verify that one or more per-scope switches are also interfering?
  • Keep in mind that the per-scope switches are independent of the matrix filtering switch, so stuff can still be blocked/modified when per-scope switches are enabled.
• Did you try to bypass the browser cache when you forced a reload of the page?
  • Sometimes it may be necessary to tell the browser to bypass its cache.
  • For example, see https://github.com/gorhill/uMatrix/issues/893.
  • Firefox-specific: I also found that sometimes opening the broken page in a new tab fix a breakage issue.
• Did you enable matrix filtering in the behind-the-scene scope?
  • If you enable matrix filtering in the behind-the-scene scope, you may suffer more obscure breakage as a result.
  • As mentioned above, using the logger is key.
