  • solution: execute the file: setup_xampp.bat to relocate the xampp

upgrade xampp

• re-check the installation file path of xampp in the conf files of Apache, PHP, Mysql (ex: xampp was installed at d:\xampp, the conf files was written as d:d:\xampp) [XAMPP v1.7.5]
  • filezilla server: {xampp}\FileZillaFTP\FileZilla Server.xml
• Move the folder of old PHP extension files and install new one after installed new version of XAMPP. Else the folder of PHP extension files will not be overwrote during the installation. The missing PHP extension will cause Apache starting-problems
