Hello @rene-michaels
Hope you’re doing well today! Thank you for reaching out to us.
We don’t have any past reports about the Docket Cache plugin creating issues with the Hummingbird plugin. However, it is recommended that you use only one cache plugin to address the “caching” functionality of the site. Using multiple plugins for cache may result in conflicts or issues on the site.
As I checked, the Docket Cache is about Object caching which is related to the database part and ideally, if you only have Hummingbird “Page Cache” enabled it should hopefully not cause any issues. I haven’t tested the Docket cache plugin yet, but I did install it on my test site with Hummingbird Page cache enabled and observed the site for some time. However, since each site is built differently and we do not know how the plugin could affect your site, I would recommend you test it on a staging or a dev environment first.
Hope this helps.
Kind Regards,
Saurabh
