All links dead on Admin page (v7.6, new install)

Hi,
I’m planning to convert from SugarCRM to SuiteCRM. I wasn’t sure whether this should be posted as an Install problem or not???

I just set up a new server and installed SuiteCRM 7.6. (Ubuntu 16.04; PHP 7.0.4). I walked through the install wizard with the minimum necessary info (no sample data, no email config, no cron jobs, etc). It seemed to run without errors. I was expecting a plain-jane install with essentially an empty database. I can click around the application… going to various menu choices (from main menu). At first glance, it appears to be what I was expecting,

But when I go to admin page (to set up users, or play with system settings) all links are dead (non-functioning). In fact things like “User Management” “System Settings” “Email Settings” etc do not even appear to be links. I’ve tested with Firefox and IE browsers.

All I have in the system so far is the admin user created at install time. Why would the admin page links be non-functioning?

Thanks for any insights,
GP

I’ve narrowed down the problem, but I don’t know enough about the underlying code to fix this.

In the HTML, these various sections on the Admin page are broken down into TD tags. For instance, here’s a TD tag for the “User Management” selection (from a known working SuiteCRM 7.6 system):

<td width="20%" scope="row"><img src="themes/SuiteR/images/Users.png?v=MXk4kWGLvCzSEIxB_DjgZA"    border="0" align="absmiddle" alt="User Management" />&nbsp;<a id='user_management' href='./index.php?module=Users&action=index' class="tabDetailViewDL2Link">User Management</a></td>

The problem from my new [bad] server install is that the img tag is mangled… just before the “a” [anchor] tag.

Here’s my bad img tag:

<img src="themes/SuiteR/images/Users.png?v=FvJsvgMvgtIODASTTJ2pXw" &nbsp;

And here’s a good img tag (from a good 7.6 install):

<img src="themes/SuiteR/images/Users.png?v=MXk4kWGLvCzSEIxB_DjgZA" border="0" align="absmiddle" alt="User Management" />&nbsp;

This following code is missing from the trailing end of my bad img tag:

border="0" align="absmiddle" alt="User Management" />

Does anyone know enough about how this works under the hood to explain why this is happening? Or at least point me in the right direction to troubleshoot this?
