RankMath conflict with Head, Footer and Post Injections Plugin ?

Hi,

First of all, congratulations for the excellent support and development of RankMath which I consider by far the most complete and best plugin of all time to do professional SEO on WordPress and in addition it is also totally free and full of numerous functions and always in constant development and growth , thank you very much for your valuable work.

That said, in the RankMath installation wizard I get this error warning:

“The following active plugins on your site may cause conflict issues when used alongside Rank Math:
Header and Footer. Deactivate Plugin”

The problematic plugin reported in the RankMath setup wizard is this:

– Head, Footer and Post Injections by Stefano Lissa
– Official WordPress Plugin Page for Head, Footer and Post Injections: https://it.wordpress.org/plugins/header-footer/

This plugin has been downloaded over 300,000 + times, is constantly updated and has over 582 total reviews of which 561 reviews with a rating of 5 stars so it is a very used, tested and reliable plugin with active support service.

These are my 2 support questions that I ask you:

Question n° 1:
I kindly ask you specifically what all the RankMath problems are if you also use the plugin Head, Footer and Post Injections ?

Question n° 2:
Based on what you answer about my first question, my second question is can you use the Head, Footer and Post Injections plugin or not ?

I look forward to a complete and comprehensive response from the assistance of your Development Team.

For the moment I thank you in advance for the support you will offer both to me and to the whole community of users who use RankMath.

Good day and good work.

Sincerely, WNS.
