Fatal error: Uncaught TypeError: array_merge(): Rankmath: I know that when some problem occurs in your earning blog, you start hustling. And consider it as if a mountain has fallen on you.

Then you try your best to fix all these critical issues by any means possible. If this problem is caused by the conflicts of the plugins in WordPress, then it can be easily fixed. But if the problem has happened inside a particular plugin, then your problem increases a lot.

Recently, such a problem also happened to me in which some internal issues started coming in my Rankmath plugin, and I started trying to find their solutions.

Critical Issue 1

In the above picture as you can seen that whenever i try to open any rankmath settings the same error message generated. That was the worst situation that i ever have faced in my entire blogging journey.

But don’t worry if anyone of you are facing such critical issue regarding Rankmath plugin, I have the solution, so sit calm and don’t panic at all. I’m here to help you.

Steps I Follow To Resolve: Fatal error: Uncaught TypeError: array_merge():

After getting stuck in this problem and the steps I took to escape it, I present them individually through this post.

So that you can also have some ideas and if you are thinking of getting the work done by paying money to any developer or agency, then you can avoid all that.

Because in this situation, no one will help you. They will just waste both your time and money. Here are the steps that i followed,

Step – 1. I Tried To Remove and Re-Install All Plugins

First of all I did what everyone does, I tried removing all the plug-ins from my website. Although the website started working well after removing Rank Math, but now it was all about my SEO.

Because I have taken the paid version of RankMath. And if I use any other plugin like Yoast SEO, All in One SEO, etc., then my RankMath SEO data cannot be imported in others.

Which was a serious problem for me. That’s why I failed to do this.

Step – 2. Taking Help of Hostinger

After this, I talked to the live specialist of my hosting provider, hostinger, and told them about my problems; although they helped me, I did not get much benefit.

Then they advised me to hire the hostinger’s development team or any developer from Fiverr.

Step – 3. I Heired Hostinger’s Development Team To Fixed Issues

Now, I have hired the development team of Hostinger. Hostinger Live Specialist helped me in hiring it. They charged $50 for it, plus tax.

I told Rank Math about this problem, and they told me that they had made some new updates in their plugin, due to which there may be some problems in the old plugin, and they advised me to update the plugin.
