When I want to add a new content block there is no option on the page for adding and editting a block , I have some other content blocks that have been created before and now are active but when I want to edit them nothing is shown and I just see the block name and shortcode thats why everytime I need to test some of the blocks on the front end to find out the right one if I want to use it on a new page . What should I do now as Iam not able to create any new block. thanks
