Hi @loveleentak,

This line indicates that there are problems with one (or more) of the plugins. Probably invalid or missing version.xml file, although I’m not sure. First of all I’d check systematically this file in every plugin, e.g., https://github.com/pkp/ojs/blob/master/plugins/generic/browse/version.xml#L15
Then I’d check correspondent column in the versions database table.
