Solution for this topic
Sorry to hear of the problem you are having.
Are you using HTTPS on your site?
This can be due to misconfigured HTTPS.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
Could you please share me your site URL where it’s happening so that i can troubleshoot it?
