Conflict with Frontier Post Pluging

When activated along with the Frontier post this plugin breaks the frontier code short code. I have contacted the Frontier plugin author, Read this post on the forums: https://ww.wp.xz.cn/support/topic/two-errors-with-frontier-post-shortcode?replies=27#post-8195681

But he couldn’t find anything.

I have a test and live site. You must be logged in to contribute so I cannot provide a page link. I can credentials if you wish. The test site has your plugin enabled.

I hope you can help, I really like your plugin.

Thanks
