Hi! I’ve noticed that when different blogs on our MU install post and our root blog makes an entry using sitewide tags that sometimes random categories are also being created. They always take the form of the number such as 123, 66, 84, etc. The numeric categories don’t show up on the original blog or in their dashboard, it only shows up on our tag blog, which happens to be the root or main blog of the install. Any ideas on why this might be happening or if anyone else might have experienced this? Any feedback appreciated!
