According to Joomla Admin my version of Joomla is:
Joomla! 1.0.13 Stable [ Sunglow *eCommerce Edition* ] 21 July 2007 16:00 UTC
I paid and downloaded SEF patch for exactly this version of Joomla.
Installation went OK but configuration of SEF reports Joomla version error as follows:
Configuration file could not be edited!
Reason: Incorrect Joomla version
Please contact email@example.com
for the correct version (first check your version before contacting Joomlatwork)
Version support within this component: Joomla! 1.0.13 Stable [ Sunglow ] 21 July 2007 16:00 UTC
If you need my purchase # let me know.
