At first I could not understand why every time I uploaded an image and inserted it into a standard wordpress theme post or page it would not appear in the visual editor window.
So I deactivated all plug-ins
Then attempted to replicate the problem edited page or post --> visual editor is accessible with all the icons and no problem inserting images which were visible in the visual editor.
Also was able to switch between the visual editor and Text editor no problem
After updating the edited page which was left in the text editor position I proceeded to plugins list
I started at the top of the list of plugins installed all deactivated
activated first plug-in in the list and attempt to troubleshoot by replicating problem
Turned the only activated plug-in off and went down the line one by one until all plug-ins were individually tested against the issue.
With all plug-ins disabled except for when I activated and tested the WooCommerce plug-in the behavior I noticed was the inability to switch between the text and visual editor.
I further tested deactivating WooCommerce plug-in and found I could then switch between the text and visual editor.
I could successfully insert images which showed in the visual editor.
Leaving the admin panel with the visual editor selected I then activated the WooCommerce plug-in
The problem was reproduced and although the visual editor was selected all icons had disappeared in the visual editor.
All attempts to insert an uploaded jpg image in WordPress theme page or post failed to display.
While the WooCommerce plug-in was activated i found it impossible to switch between the WordPress visual editor and text editor.
As soon as I deactivated WooCommerce I was able to insert images again to pages/posts
I did not try these tests in any WooCommerce pages only the standard Theme pages/posts
I have an example screen grab showing the source code of the page with visual editor broken WooCommerce activated
screen grab of admin interface same page with WooCommerce deactivated
Since I added the image to page below while WooCommerce was deactivated the page will still display image correctly after activating WooCommerce again
