Hi,
Same thing for me too, straight after updating.
To get the site back up I had to delete the plugin from the file manager in the host cPanel.
As I’m using a theme that depends on Redux, my site now has no bespoke css.
Tried to activate the redux update again and this happened:
Plugin could not be activated because it triggered a fatal error.
Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in /home1/maldive2/public_html/wp-content/plugins/redux-framework/ReduxCore/inc/themecheck/class.redux_themecheck.php on line 193
So, I’m looking to get a previous version.
