Hello,

This is just an FYI, and a follow-up to https://rolandd.com/support/ro-csvi/can-t-start-import-no-button-to-click, which can no longer be found. The issue was unresolved.

The problem was that no buttons were appearing in the toolbar on the import preview page (see attached), so the import could not be started.

The cause turned out to be the Regular Labs Advanced Module Manager extension. It has a line of code to check for which admin modules to allow which checks for any task which equals 'preview':


&& \RegularLabs\Library\Input::get('task', '') != 'preview'


Since we're using Joomla 4, the resolution was just to modify the importsource and importpreview controllers in RO CSVI with a task that was not exactly equal to 'preview'.

BTW, there's also a line in /administrator/components/com_csvi/views/importpreview/view.html.php which should probably reflect the page the script is on. It is line 95, in the toolbar function, which should probably be:


ToolBarHelper::cancel('importpreview.cancel');


instead of:


ToolBarHelper::cancel('importsource.cancel');
