I have just installed JS Pro on a virgin Joomla 3.3.6 install running under Plesk 12 on a Windows 2012 VM in VMWare 5.5
The system is snapshotted in VMWare and backed up within Plesk if a rollback is needed
JomSocial is installed on the nominated supportable site and I am on day one of my six months support
Problem:
The install created a main menu link
When clicked, the link correctly specified in the menu manager is ignored
- rather the alias is appended to the site root (hence yielding a 404)
I have tried manually adding community menu items to yield the same result
Other non-JomSocial links work okay
Please check again, should work fine now, this issue caused by "Use URL rewriting" on Joomla config, I alraedy set to No, if you want set to to Yes, you should change htaccess.txt to .htaccess on Joomla root.
