Source code not appearing when editing author guidelines - OJS

Hi there,
I am using OJS version and I would like to edit the source code of the Author Guidelines.

When I access the Workflow and then Author Guidelines, the option to edit the source code is not appearing:


It appears when I edit the About the Journal section, but not for the author Guidelines.

Can anyone help me with this issue?

Thanks a lot in advance.

Hello Luisa,

It looks like other journals have had this problem as well - in an earlier thread about the issue, the Text Editor Extras plugin seems to help. Please give it a try.
