Does this plug-in work with Headway?

Hello sarar,

Any developer can’t give you the guarantee that his code will not conflict with anything.

We didn’t test our plugin for compatibility with Headway. We don’t know
why Headway appears these errors at your site.
Please contact theirsupport service.
Please note that we can also help you if you really need this, but
this service should be paid since we need some time to investigate the
plugin and make the necessary changes.
Looking forward to your reply.

Kind regards.
