Hello,
The issue has been narrowed down to one of the most recent theme updates of Porto not being compatible with the plugin we use (Flyingpress) which is for speed optimization. We use the same plugin on our other sites and we haven’t had any issues. But with this site the issues resolves as soon as we deactivate the plugin.
I spoke with support from Flyingpress and gave them access to a staging site we created for this testing purpose. They narrowed down the issue to the theme and asked to roll back to the previous version which I did do on our live site temporarily, but it’s not resolving the issue.
