Confluence is installed locally. H2 embedded database is used.
Everything worked fine, but after one reboot, instead of the top menu, the message $soyTemplateRendererHelper.getRenderedTemplateHtml("com.atlassian.auiplugin:aui-experimental-soy-templates", "aui.page.header.soy", $templateParameters) appeared.
I found this article Missing buttons inside the top bar with "$soyTemplateRendererHelper.getRenderedTemplateHtml" error message appears instead. It says that you need to connect to the database. I found another article Embedded H2 Database that says about using DBVisualizer.
I installed DBVisualizer and tried to connect to the database and got an error
An error occurred while establishing the connection:
Long Message:
Ошибка ввода/вывода: null
IO Exception: null [90028-199]
Details:
Type: org.h2.jdbc.JdbcSQLNonTransientException
Error Code: 90028
SQL State: 90028
Confluence works, all articles are available, but there are no header and comments.
How to fix the problem?
