I keep seeing this error on my main blog url:
<b>Fatal error</b>: Unknown: Cannot use output buffering in output buffering display handlers in <b>Unknown</b> on line <b>0</b>
It doesn’t always show up, but regardless this is a problem.
How do we fix this?
Sorry to hear of the problem you are having.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
Also please make sure you are using latest version of PHP on your web server.
