error_log

Guten Morgen,

I have a small problem which has been constantly reporting in the error_log and I have no idea why or how to fix it and would appreciate some step by step help, if possible.

Here is an extract from the log:

[27-May-2014 21:00:03 Australia/Adelaide] PHP Warning: Smarty error: unable to read resource: "" in /home/neigh/public_html/core/smarty/Smarty.class.php on line 1093

- what would cause this?
-how do I fix it?

Danke and regards

Don
