Hm, this user account "Stackideasdev" already blocked from your site, this is why i always hitting this error when i trying to login from your site backend.
Login denied! Your account has either been blocked or you have not activated it yet.
Perhaps you can try temporary rename these following folder then try upload latest Easysocial launcher installer from your site backend installer page and see whether can installable or not.
- JoomlaFolder/administrator/components/com_easysocial
- JoomlaFolder/component/com_easysocial
- JoomlaFolder/media/com_easysocial
If still doesn't work, it might be hitting another different issue, since i was unable to login from your site backend, i can't tell you what is the exact installation error you facing now.
What's the best way to resolve this?
If that is really related with your file permission issue, I would suggest you that check with your webhosting provider regarding your site file permission issue, the problem was indeed an file owner/group problem, and try chown for all files and folders to the correct owners on your server.
All files need to be writable by the webserver user.
