Website is crashing

Dear Plugin Developer,

After upgrade to your free plugin 2.9.9 the website is crashing.

Before the upgrade it was working fine. I had to deactivate the plugin to keep the website online.

Can someone please look into it.

I had also upgrade the wordpress to latest version : 4.3.1 after which I had upgraded your plugin.

Appreciate all the work an effort from you towards providing free plugin.

Thanks
