Hello,
Have you checked the .htaccess file in the wp-content folder and the .htaccess file in the root folder? I am new to the forums but if you still need help, we can get it fixed.
Version 5.4 here on apache and having the same issue. As a temporary fix, I am changing the default options loaded when it can’t load the configuration JSON file. Will let everyone know if it changes again or if it keeps working as usual after that. If the author gave up on this project, does anybody know the process of taking it over or forking it? I would be glad to support and improve this plugin (or others).
