Yes, you cannot have spaces in the name of a custom block. The form won’t save that way.
If you create a block, remember to add it to the sidebar further in the appearance section of your Website settings. It won’t show until you drag it over into the sidebar.
I have other jounals that can rename the custom block with spacebar. Its on clean new instalation on ojs 3.1.
This journal on 3.1.2 i cannot put space bar. I also cannot rename the spacebar and the title doesnt appear.
Above the scopus logo there supposed to be a title.
