Hi   I have installed Uniform Server on my PC and have installed a packaged version of Joomla 1.5 from Rockettheme which includes a theme.   This has been running successfully for over a week.   I installed a joomla extension called AceSEF and followed the instructions which included turning on SEF and Use Apache mod_rewrite in the Global Config screen. I changed the name of the htaccess file to .htaccess as instructed.   AceSEF then reported an issue with the .htaccess file - but did not specify what.   In the fron end all the links other than the home page returned a 404 error.   Turning SEF off in global Config made the links work again.   To test this i have also uninstalled AceSEF and replace the htaccess file with a new version from a clean copy of Joomla.   The same issue persists - turning on SEF causes problems   Is this a limitation of using Uniform Server on a local host? or is there something else i need to do?   Please Note: I am not a programmer so will need instruction to be clear.   Thanks in advance for any help recieved
