I am getting the message included below each time I try to upload images to Flickr (which I have tried MANY times) over the past couple of days. I have tried deleting and reloading the plugin, disabling/enabling, reloading...nothing has worked. In the plugin manager it says "Flickr Installed; May Not Work" If I click "reload the plug in" it temporarily says it is running, but then goes back to "Flickr Installed; May Not Work."
HELP. Losing my mind with this! I just uploaded probably 200 images last week-no problem. Now this.
Oh, ALSO have tried reseting Safari, removing cookies, reauthorizing the plugin through Flickr...
This is a long-standing bug in Flickr's servers out of Lightroom's control. See this topic in the official Adobe feedback forum: Lightroom: Publish to Flickr results in multiple errors
Wait a minute or two and retry. Then wait a couple of hours and retry. Then wait a day or two and retry. The error will likely go away.
Flickr has been getting more and more unreliable over the last year or two as Yahoo enters its death spiral. The just-announced layoffs of 10% of its employees will likely further squeeze Flickr.
