THE CAUSE:

What Causes The Plugin could not be activated because it triggered a fatal error?

A fatal WordPress error can be caused by a number of factors, such as:

WRONG CODING

A poorly coded plugin will cause problems no matter what theme and plugins you use.

COMPATIBILITY PROBLEM WITH WORDPRESS CODES

The plugin code may be incompatible with the code used in the main WordPress files. In this regard, most plugin developers update their plugins after the release of a new version of WordPress to make sure that their plugin is still compatible. Unfortunately, many plugin developers do not do this, so you need to be especially careful when installing old plugins.

COMPATIBILITY PROBLEM WITH ANOTHER PLUGIN

Plugins do not always go well with each other, especially when plugins offer similar functionality.

COMPATIBILITY PROBLEM WITH YOUR THEME

Many features of the theme are placed in the theme functions.php the file. The principle of extending the functionality of a theme using functions is the same as adding functionality using a plugin. Thus, problems may arise if it is poorly encoded or conflicts with another plugin.
