Hey Imran,

I am really sorry for the delay of this reply as it is a weekend for us here.

I already help you updated to latest version of Easyblog, the reason you hitting this issue is because this table `#_easyblog_acl_group` got 5222957 records, so it hitting timeout issue in installation process.

After I truncated it, the installation work fine now.
