Hi Patskie, and Asura!
I've done changing my flux cp to CalciumKid flux CP and the result is the same. I couldn't login and register. However, I checked ./data/log/error, It said that the CP doesn't recognize my database name because of my database name consist of two spaces e.g. "example<>example<>example". Finally I changed my database name into non-spaced database name and Everything work normally! Yuppieee!
The next day, I saw my Xampp Control Panel said that the apache should run in administrator service to make it optimal. Therfore, I followed the instruction. After I ran the xampp CP in admin service, I clicked the box with "X" (cross) symbol, and something installing in my PC, The cross symbol changed into "checked" symbol.
I thought everything was ok until I was planning to resetlook via Flux CP. When I was trying to login, I couldn't login. So does when I created new account, it says the recapcha doesn't match.
I'm still trying what wrong with the CP right now.....
