For some reason one safety mechanism kicked in and turned on the Force inline styles option on the Compatibility Options panel. Apparently the cache plugin didn’t like that and decided to just skip the search style alltogether.
Anyways, I fixed that by turning it off: https://i.imgur.com/29AyRsQ.png
In case you experience that after a future update, please check if that option is turned OFF and clear the cache. It turns ON automatically if it detects an issue with the file permissions – it must have been triggered by a false positive detection.Best,
