The newer version of WordPress 3.4.2 was updated on our website by another staff member, however it is not supported and a lot of the tools are not working when editing a page. No options for adding a new table or cell appear. Can not click on the HTML tab to edit. Can not even see what is already there. Although when I view the website, everything is there and fine.
Need to either undo the update or other suggestions. I would prefer not to have to restart everything from scratch if possible.
