Every time we add some character which is not an English character, we can no longer edit site content (see the screenshot http://joxi.ru/82Q7vy0SwRYEqr).
Now I have a need to edit Masthead, since I can not do it via dashboard, whrere do I find its content in the database?
If you are really running OJS 3.0.0, I would strongly recommend that you upgrade to a more recent release of OJS 3.x. You will find substantial feature enhancements and bugfixes. I suspect this would be among them.
If you were to edit the content directly in the database, I think you would find it in the table
journal_settings. The content should be keyed by
setting_name is probably “about”. I do not recommend this approach.
