What is Simple Pie?
SimplePie provides a feed parser which is bundled with WordPress. It handle the RSS feeds which can be used to syndicate content across web sites.
What has this got to do with WordPress?
WordPress has bundled SimplePie 1.3. This worked fine for many years. However when running under PHP 7 this creates warning messages when parsing dates.
The problem was fixed in SimplePie in 2018 but WordPress has not yet bundled a fixed version of SimplePie into the core WordPress release.
Slickr Flickr includes SimplePie
Slickr Flickr 2.7 includes a bundle of SimplePie 1.5.4 so the warnings no longer appear.
