ah, the self:: part might explain it - I might have used php5 specific functions. What if you put one letter in the search field, or maybe even a space - so, it will override the default?
I have tried every option and none of it works.
You had used "clean" as the op and strings in various places, and I thought "clean unused blogs" was more exact.
I would agree with this. BTW I would call this plugin Clean Unused Blogs instead of just Clean, so that it is clear what this plugin is used for and not confused with the Clean features that are built into Lifetype.
Thank you guys for all the work on this.
