Re: Error on admin panel

Is this a fresh installation? What version of Magento are you running? Do you see the problem every time you login? 

 

Something is turning on output buffering: http://php.net/manual/en/function.ob-start.php

 

You may be getting some other errors like the "out of memory" but as buffering is on, the error may not be shown.

Is this a fresh installation? Did you do anything before the error happened? 

Re: Error on admin panel

Yes, I installed my store before 2 weeks.
