I am really like your theme because it looks great and has some very cool functions. When I activate the theme everything is fine but when I start to install/activate the swift framework plugin I get only whitescreen with error message: “FATAL ERROR: allowed memory size…………..wp-db.php”.
I got enough memory so that shouldn’t be the problem. Also try to disable the page builder but didn’t changed anything. Maybe you can take a look into it? Actually another theme is activated but you can just change the theme and try installing the swift framework plugin.
It is important to get the logs information, to see the reason of the crash. Ask the error logs to the hosting company and attached them here in a reply.
