Problems RankMath and Mailster (Newsletter Plugin)

  • I have one installation of fresh versions: WP 5.3.2, RankMath 1.0.38 and Mailster 2.4.8.

    Believe me, I tried everything before. But only if I deactivate RankMath the Visual Template Builder of Mailster was visible (again). You see documentation and screenshot at official website here:

    There is a demo site, open and you see the section “Template”. This is the problem. With activated RankMath there is only the tab / title and after this “nothing” to see.

    I cannot give you any errorlog warnings of my server. There are none.

    But in inspector of chrome I can see something. Please look at the screenshot: null, again only the link to the screenshot:

    I would appreciate if you can solve this problem. Together with the team of mailster, I suggest.

    Did I mention this is an urgent to solve problem?

    Thanks in advance.
