I've attached an example of one of them.
When I try to save the widget, I get the error
Incorrect responce
ForbiddenYou don't have permission to access /base/ajax-component-admin-panel/process-queue/ on this server.
Well I've had a search and thought that it may be a permissions problem or my host blocking something, but if I remove the javascript and use plain HTML, the widget saves with no issue, so that logically rules both issues out. Any idea anyone?
