Hi,

I've been using JoomSEF with the SEF patch extended component for at least a couple of years on a site but it's suddenly started throwing the following errors:

PHP Fatal error: Call to undefined function includesef() in /components/com_sef/joomsef.php on line 159
PHP Fatal error: Call to undefined function xmlparsing() in /components/com_sef/sef.php on line 150

This seems to have started when the SEF cache regenerated.

I've run file comparisons and the files haven't changed since the components were installed. The web admin added a few new urls via the SEF Patch component a few days ago but apart from that nothing has changed with either the webserver or the Joomla configuration. Google is also drawing a complete blank on these errors so I'm a bit stuck! Has any one got any ideas?

I'm using:
Apache 2.2
Joomla 1.0.12 (I know it's very old, we inherited the site!)
JoomSEF 2.2.0
SEF Patch Extended v1.0

Thanks,
Duncan
