When going to the shares and clicking one, I cannot remove the share. Same is for shared links, where I cannot click the “Share Link” button. I’m not sure how I can remove it. It seems broken? Previously in NC 13 it was in that menu…
Okay, so this seems to be some really weird issue.
I could fix it! But I’m not sure if it is permanent. I had to do the following things:
Locate the HTML where the buttons would be
Select the share-menu item and look at the CSS properties. You’ll see that display: block is striked through, which means that some other rule overwrites it.
There is a display: none!important attribute in some other element that affects this element. Disabling it in the browser F12 window fixed the error.
It seems that after doing this, the display:none!important attribute doesn’t get added back after a page reload, which is good.
Okay, I found the problem. Just tried opening the site in another browser window in private mode. I use Firefox 64.0, the current latest one.
I see the following CSS rule:
This rule looks like a filter rule, since it’s pretty large and has this !important flag there. So I tried to disable uBlock origin, and voilà, the buttons appear. Note: uBlock origin did show 0 of 0 elements blocked which would actually mean that it didn’t block anything. But in fact, it did…
Wow, what a bummer.
Great job finding the root cause! I will keep uBlock origin in mind in case somebody else stumbles across such an issue and reports it here.
If someone else runs into that issue: Instead of disabling uBlock completely, one can hit that button there in the settings menu to disable “cosmetic filtering”. This is the feature that inserts these display:none!important flags everywhere.
