I just had an idea about this. The error message says that the calling
signature is wrong. That could happen if you don't have *PyQtWebEngine*
installed for some reason. In that case, VR3 falls back to a different
widget, and that widget uses a different signature, the one that your error
message shows. Although it normally gets installed when Leo is installed,
I have known cases where the WebEngine was missing.
It will take a bit of finagling for me to test this, which I will do
later. In the meantime, would you check to see if *PyQtWebEngine* is
installed? Here are two ways:
1. In a console, run this command (you system may use *py* instead of
*python3*, but use whatever name you normally use):
python3 -m pip list
There should be a line like
PyQtWebEngine 5.15.4
2. Run a Python session, and run these two lines:
from leo.core.leoQt import QtWebKitWidgets
print(type(QtWebKitWidgets))
If the response is <class 'NoneType'>, then you do not have PyQtWebEngine
installed. You would install it from a console with this command:
py -m pip install --upgrade PyQtWebEngine
In fact, it might be worth doing this even if you do have it installed,
just in case an update might fix something that isn't right.
