We have Sugar Versions 6.5.16 on Server 2012 running PHP 5.5. I am getting the error when opening attachments "Unable to return chart data, invalid xml for file cache/xml". I have read numerous articles with the issue being with PCRE and have made numerous changes to the JsChart.php file as noted in previous post and still the same issue.
We had sugar on an Old Windows 2008 R2 server and it worked perfect. All we did was package up the code and move it to new server. I am out of options and have to get this to work so any help would be greatly appreciated.
FYI if I browse via FTP to the attachments and open they work perfect so it is only accessing the attachment via the CRM!
This is the error we get when opening attachments:
