+is a list of probable causes and recommendations:
 
- - X display issues (may require the headless subpackage)
- - Permission issues (unable to run or connect to LibreOffice or read/write)
- - SELinux issues (SELinux prevents you from connecting to LibreOffice)
- - Nginx/PHP-FPM issues (You can execute unoconv in terminal, but nothing happens when you use a PHP script. You may need to declare your PATH. Read https://github.com/dagwieers/unoconv/issues/87#issuecomment-18800070) 
+ - Use the latest version of unoconv (or GitHub master branch)
+
+ - Use the most recent stable release of LibreOffice (less memory, more stable, fewer crashes)
+
+ - Use the native LibreOffice python binary to run unoconv
+
+ - Hardcode this native python path in the unoconv script shebang (or ensure PATH is set)
+
+ - Ensure that the user running unoconv has access to its HOME directory (ensure HOME is set)
+
+ - Test with SELinux in permissive mode
+
+It is recomended to open the unoconv script and modify the very first line to
+point directly to your installed LibreOffice python binary, so replace this:
+
+    #!/usr/bin/env python
+
+with something like this:
+
