Hi Dennis,
Ben here from LeadPages support! We are sorry that you are having this issue.
I see that you have an open ticket with our team and we will do some troubleshooting to determine the root cause.
In the meantime one thing you can try is to log into LeadPages and re-save your affected/published pages.
I upgraded my test WordPress site to 4.2.3 and was able to publish a LeadPage without issue. There may be a plugin conflict as well.
Thank you for your patience as we are looking into this issue!
Kind regards,
Ben
