Im using one of Retard's themes and lately every single client update has been breaking it. I dont know details but he had to fix it every time.
This update was not an exception, it broke again, just standart "error has occured and was reported" message with big OK button. HOWEVER, it had those shiny button which said to always use current theme and ignore the message and i was stupid enough to click it at the first launch (did not know it would break my theme yet). There was a message that said how to fix stuff if it break and i tried to memorize it, clicked ok and saw the error message. So now my client is bricked cause i dont have the broken theme message anymore (cause i clicked shiny button) not do i see the how to fix message as well. Just an error. RIP
