My micro.blog feed wasn’t updating. I found that there was a WordPress error with my jsonfeed plugin. Turns out the jsonfeed wordpress plugin on github is a newer version. Updating didn’t actually fix the problem. Checking the WordPress error log showed that there was an error with the Simple Location wordpress plugin. Error has been reported on GitHub issues.
Update: 5/28/18 This issue has been fixed in the latest release of the simple location plugin.Also on:
