Site crashes after 1.4.17 update

Hi there,

We’re currently using Popup Maker 1.4.15 on our site. But when we update to 1.4.17, the site crashes, showing a blank white screen.

We deactivated all our other plugins to rule out a plugin conflict issue and also tested the plugin update on the Twenty Sixteen theme, but the same thing happened.

We’d really like to keep on using your plugin, but we’re not sure what to do now.

We were wondering if anyone else has reported the same issue, as we’d appreciate it if you could give us any advice on how to fix the issue?

Thanks
