Hi, Sorry but I think you have misunderstood the problem.
The site menus are fine. If elements were missing from those, that would be an easy fix.
My problem, which ultimately led to all the visual issues and broken store, is that the ‘Home’ and ‘Updates’ options are missing from the WORDPRESS menu.
In the image below you will see a screenshot of my WP dashboard with the new version of X installed on my Musicmanproject site:
You can see that in the black WP menu to the left of the screen the ‘Home’ and ‘Updates’ options are missing. This means I no longer have the option of updating my themes and plugins.
In the next screenshot, taken of the WP dashboard of one of my OTHER websites NOT using X:
…So you should see in the above image that ‘updates’ appears as expected, in the black WP dashboard menu on the left.
As I mentioned in a previous reply, to test this further I made a new subdomain, installed latest versions of X and Wordpress but did not import any site content. The problem still persists - there is no option to update in the black WP dashboard menu.
I look forward to hearing your thoughts…
