Warning: Creating default object from empty value / Cannot modify header informa
-
Hey WordPressers!
We’ve started getting variations of the below error, all pertaining to line 29 in a theme file (the creators dont seem to be around anymore so I can’t contact them for support) and my php isn’t advanced, so I’m not sure what’s wrong with this line of code or how to fix it.
Example error:
Warning: Creating default object from empty value in [datebase]/wp-content/themes/ronneby/redux_framework/ReduxCore/inc/class.redux_filesystem.php on line 29
Warning: Cannot modify header information – headers already sent by (output started at [datebase]/wp-content/themes/ronneby/redux_framework/ReduxCore/inc/class.redux_filesystem.php:29) in [datebase]/wp-content/themes/ronneby/inc/lib/CompileLess/CompileLess.php on line 39Sometimes it shows other similar errors, but the offending line is always class.redux_filesystem.php on line 29
Line 29 reads:
