I have QGIS 2.18.16, in Arch Linux; I wanted to use the qgis2web plugin and I realized it is not working anymore (it used to work last time I used it a few months back) I get the following error
cannot import name QtWebKit
I have QtWebkit installed - not sure why it cannot find it; as a side note, with the developer version qgis2web works fine (but not all needed plugins are available, so I cannot use it)
