I have this message when I activated Insight Core plugin :
"Gateway TimeoutThe gateway did not receive a timely response from the upstream server or application."
Could you solve this?
Please send your reply to my webmaster : firstname.lastname@example.org.
I have deactivated all your 3rd plugins and see the insight core plugin is still working well.
Also your site is using old theme/plugins version. Please update your system to Version 1.4.2 – April 22 2019 to make the theme work best.
