After switching Perishable Press to its current home at A Small Orange, I began noticing an unusual problem with referrer data displayed in Mint. Specifically, the first item recorded in the XXX Strong Mint data panel — for both “Most Recent” and “Repeat” views — displayed several thousand hits for various site resources, all from the following IP address:
Apparently, this particular location represents an invalid “loopback address.” The requested resources appear valid, indicating typical traffic patterns, but the loopback address is not the actual referrer. This issue was preventing Mint from accurately recording mountains of vital referral data.
Researching this issue reveals that the underlying problem involves the switching of a Mint installation between a 32-bit server and a 64-bit server. Installing Mint on either type of server without switching to the other should not trigger this problem. It is the switch from one to another that results in the generation of the loopback address.
Fortunately, there is a straightforward fix for this issue. Open your Mint database via phpMyAdmin (or whatever you prefer) and execute the following commands (don’t forget to backup your data before you begin!):
1) Within the
mint_visit table, make any changes needed to ensure that all of the following fields display a value of
UNSIGNED for the “Attributes” column (see screenshot):
mint_visit table. In phpMyAdmin, open the
mint_visit table and click the “Empty” tab (located in the upper row along with other SQL commands). Theoretically, Mint’s default settings will eventually flush out the invalid referrer data, however it may take several weeks or longer.
That’s all there is to it. After completing these steps, I saw immediate resolution of the issue. The
127.255.255.255 address disappeared from the referrer data, as did the thousands of associated entries of requested resources. Moreover, I implemented this fix several months ago and have not experienced any ill effects or repeat issues whatsoever. The referrer data has been repopulated with accurate data, and Mint is once again a virtually flawless piece of statistical software.
