Hi Wendy

What happens when you try to post to LinkedIn? Is there any error message?

Is the problem limited to just LinkedIn?

I click on the field where it says Start a Post and I get a the pop-up window but then it disappears and the whole screen goes grey. Until I click somewhere, then it the screen goes back to normal.

Do you have AdBlocker Ultimate installed?

I have AdBlock Plus installed. Have had it a long time.

Try disabling AdBlock Plus. There is a known issue with AdBlock Ultimate so your extension may have the same issue.

If it isn't that, try restarting in troubleshoot mode.

It worked! I disabled the AdBlocker Plus and now I can make a post. Thank you for troubleshooting this!  :)
