I just updated my Ajax Pro to Version 4.24.1 and I am having a similar issue as before. The live staging site at https://staging7.gracei13.sg-host.com/ appears to be unaffected but who I am inside my WP admin editing a page the header is having issues. Please see screen shot. Please advise. Thanks. FYI, I still have the fix in place that you recommended before. I have tried reverting that and it has no impact.
