Template forums/front/index/forumRow is throwing an error

[Nobiliana]

Suddenly, the forum is giving errors since this morning.

Frontpage: [[Template forums/front/index/forumRow is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]

After trying the support feature in the admin cp nothing has changed.

Then I wanted to set the forum offline and I got the info that the offline message will be given as

[[Template core/global/forms/editorRaw is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]

I have no idea what happened as I have done nothing.

Have enclosed a pic of the front page.

Has anyone possibly an idea how I can solve the problem?
