Hi All, All my local PHP sites (http://127.0.0.1/... and http://localhost/...) worked until today. Now all these local sites don't work anymore. The only difference since yesterday is running 16 Windows Updates. I checked C:\WINDOWS\system32\LogFiles\W3SVC1\... but no errors. Can I set a php.ini setting to track down the problem ? Or where else to look to solve this problem ? Configuration: Windows XP SP3, PHP 5.2.0, IIS 5.1, MySQL 5.0.15 NT Any help highly appreciated !!! TIA, Cor
