The service being provided is from The Events Calendar plugin.
The error means that The Events Calendar was upgraded, but Pods was not, so the integrations are no longer compatible between the two versions.
Either reverting The Events Calendar, or upgrading Pods to at least version 2.9.18 should resolve the issue. 2.9.19 may be better, as it was released five days later with a fix which could effect some caching mechanisms filling up.
2.9.19.1 contains security changes may require more careful review, as it closes potential security holes if an untrusted user is able to publish shortcodes, but the hardening against that vector requires some consideration of where and how shortcodes are used. The release notes of 2.9.19.1 also lists additions between that version and 3.1.
The current version is 3.2.1.
See https://github.com/pods-framework/pods/issues/7105
For what it’s worth, Pods no longer uses that shared library in Pods 3.0+ so it will no longer conflict with any other plugins like that.
Thank you both! Now I have to figure out how to apply those updates without the benefit of the WordPress interface…
Hey, I should report back. I downloaded the files and dropped them into place, then restarted the site without plugins. When I turned the plugins back on, it found the right files and everything worked again.
Thanks!
