Non-issue In my Error Log

[phred]

I see the following in the Error Log at least once a day, sometimes more. There's no pop-up when it happens and it doesn't seem to cause any issues. Looks like it might be plugin related. Should I (or you) be concerned?

no concerns for MB itself - its a bug in one of the plugins which only the plugin developer can comment on whether it matters and if a fix can be done

Thanks. I guess I have to disable them one by one in order to find the culprit.
