Hi @rossty

The WordPress Core Trac isn't really the best place to seek support for plugins. You should use the support forums (if you're a Free user) for that.

If you're using Smart Slider 3 Free, you can open a support topic here:
​https://wordpress.org/support/plugin/smart-slider-3/
But if you're using Smart Slider 3 Pro please contact us here:
​https://smartslider3.com/contact-us/support/

Based on your screenshot your issue might be a conflict with the Post Grid Combo Plugin:
​https://wordpress.org/support/topic/output-buffer-error-2/
We already reported the problem to them and are waiting for them to sort it out. In the meantime you could apply the suggested solution.

If you don't use the Post Grid Combo plugin then please seek supoort on one of the mentioned channels above.

Hi @Otto42 Thanks for the response, I think there is no issue with my post grid combo because the problem occur when I used the W3 Total cache plugin. and After uninstalling the w3 total this error occur to my Smart slider admin.

Based on your error, it looks like this is likely related to the following url, a conflict between Smart Slider 3 and Post Grid, ​https://wordpress.org/support/topic/output-buffer-error-2/

WordPress core Trac isn't the correct place to seek support however, and no-one here can help you directly.

Please see the supports links that @nextend_ramona (a support rep for Smart Slider 3) posted above for your next steps.
