On Jooomla! 3.7.0 some Visforms user get an Error "404 Component not found" when they try to go to the Visforms cpanel in the administration of their website either with new Visforms installations or updates.
Obviously this problems only occurs rarely and is due to some specific configuration settions of the website or some specific extensions which are installed on the website. As far as we know the problem is caused by outdated cache and could always be solved, by clearing the Joomla! cache (System -> Clear Cache).
