Hey Tom,
I already consult with our team regarding this, I might be missed up some important info during meeting last time so given wrong information in my previous reply, i am sorry for that.
And I also got our developer confirmation, that is a bug for the Joomla update for Easyblog in current version, this will fix in next release version but the next release version will not work yet for example :
1. The current version 5.2.4.
2. when we release 5.2.5 version, it needed to update the latest fix file into the Easyblog updater file on your site. Mean you have to download the latest launcher installer from
https://stackideas.com/dashboard then install through Joomla installer page and proceed the installation.
3. so when we release 5.2.6 version, you can only update through Joomla updater.
