Getting an unidentified UI error message
 

As the title states, i am getting an unidentified UI error message whenever I log on with a character, just at the time I enter the game. Is there any way to find out what is causing it without having to go through the process of turning every addon off and back on one at a time ?
Thank you in advance for any advice you may provide.

What does the error message say ?

But yes usually if the message doesn't point out the culprit the only way to know for sure is to test blocks of addons until you whittle down to just the one causing an error.

Thanks for the reply, I did check everything out, it appears that the Alchemist add-on is causing that issue for some reason. I test it more and send some feedback to the developer.
