i found the culprit sir @kharisblank.. the only issue on the demo importer is the apache. i think the latest version of the apache is still not utilized meaning there is a lot of bug rather than the privious one..
the latest version of the apache block the uploading process of the demo impoter so the uploading process stop on the 32% 50% 75% then it will realese the statement “something wrong on the system”
i hope athemes will fix the issue as soon as possible..
regards..
i already fixed it.. don’t forget to update all your plugins, in my case i already double check all my plugins and they all updated, do also double check your upper bar recommendation and suggestion to update, and i missed that option that caused my website not working properly..
