I am getting the above error. The same error occurred in the main index.html file, but it was easily solved by downloading the cordova-plugin-wkwebviewxhrfix plugin. The problem was that through the wkwebviewxhrfix plugin, the XMLHttpRequest cannot load error in the main index.html file was solved, but the sub page index.html file did not solve the same error. I need a solution.
(main) index.html path : www/index.html (sub) index.html path : www/world/wikitude_AR/inedex.html
