Thank you for the responses! The issue is fixed now.

Szabolcs -- yes! That works. I'm new to Qt and did not know we can do such
a thing, but same origin policy is now disabled :)

Kai -- Although my issue is fixed, I'm still curious to try out your
method. How do I use QWebEngineScript with the QWebEnginePage object that I
have? For example, I tried to add the following code right after calling

    QWebEngineScriptCollection* scripts = &m_page->scripts();

    QList<QWebEngineScript> scriptsList = scripts->toList();

    for (int i = 0; i < scriptsList.size(); i++) {

        QWebEngineScript script = scriptsList.at(i);



But it doesn't seem to work (maybe the javascript is already finished
running before I was able to iterate through all the script source and
set runsOnSubFrames to true). Mind if you point me to the right
