Getting error when opening the Setting of the plugin

[asrarahmadehsan]

I get failed Ajax request or invalid JSON format error when opening setting of the plugin.
I am using OJS version 3.3.0-11 and PHP 8

This plugin is released only for OJS 3.2 and 3.1., so it does not work in OJS 3.3.
Due to lack of time, there is no plan to update it for OJS 3.3. (and PHP 8.x) at the moment, as we are only using it internally and it has not been published in the official PKP plugin library.

Maybe this will help: https://forum.pkp.sfu.ca/t/ojs-3-3-most-read-articles-block-plugin/70617
