Hi,

It's very difficult to provide advice unless you locate the *underlying error* behind these issues.  A 500 error just tells you that an error occurred, but you must follow the troubleshooting guide to find details about the error: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)   

If links are not working, that also implies to me that there's an error occurring (possibly in the UI).  So, following the troubleshooting guide is also the recommended path.

Once you locate the underlying error messages, you can share them here if you cannot figure out the cause.  You also should check our Common Installation Issues to see if one of the errors you find is listed there already: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues
