Sudden error 1064 for K2 component.

Two days a go when I click on an event I get this error page.

Error 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 0)) WHERE m.published = 1 AND module = 'mod_k2_eo' LIMIT 1' at line 1

It should take the visitor to the K2 item that is linked to it.
PHP version was 7.2 and was working ok. Now I lower the version to 7.1 and 7.0 and still the same problem.
I can access the K2 items from other paths with no problem.

What needs to be done?

Thanks,
