After a long time, I reinstalled IndieWeb’s WordPress plug-in – Simple Location. It turned out that it automatically added all the posts to the geographical location of my current location. This is obviously unreasonable, because these posts are written in different places. Before installing the plug-in, posts did not have geographically related metadata. Then I manually changed it according to my memory. I changed it for two and a half hours, and almost half of them. Suddenly, I felt oops. I wanted to check it back and found that it was overwritten by my current geographical location again (it is estimated that the geographical locations were automatically updated because of the editing behaviour). It is too stupid. It’s better to uninstall this plug-in, and delete the generated metadata.
