Hi Marius, thanks for your help.
I use these configuration:
– WordPress 4.9.8
– Gutenberg 4.4.0
– Theme Sixteen
Wordpress allow to switch the description of permalinks. By example:
– myblog.com/name-entry
– my blog.com/date-entry
Etc.
When I start an entry whit Gutenberg, the plugin creates the permalink using a different option of my configuration.
So, I must to exit of the entry and refresh the configuration of permalinks. And then go back to editing my entry.
Thats the issue.
