Thanks for reported, based on what i checked on my locally, it seems like I hitting that error is different from your site.

I suspect you didn't download that plugin from our download page here https://stackideas.com/downloads/plugins , because we did updated this plugin "Community Builder Plugin" which can support in Easyblog 5.x , but it still have some issue which I shown you that error at above.

When I go to enable it, CB says me: "This plugin is not compatible with your current CB version. This plugin may still be used, but it may not function properly".

And I was unable to replicate this warning, it seems work fine for me when i enabled it, you can check my attached screenshot below.

By the way, I already log this issue into our issue tracker.

Ok, I tried to download and install the plugin as you suggested and now it works fine.
Before, I installed the same plugin found in "All EasyBlog Plugins" zip package and it caused the issue.
Thank you!

Thanks for updating Giuseppe and glad that your issues are resolved now By the way, why don't you give EasySocial a try because it works really nicely with EasyBlog too!

Yes, I know...
We're going live in some days but I'm planning to test and evaluate Easy Social soon, in order to verify if it's compatibility whith our needs.
Thank you!

You're welcome.
