In version 1.6.3 a change the values in C:/XAMPP/APACHE/BIN/PHP.ini to:
max_execution_time = 3600
memory_limit = 512M
I restart XAMPP and I got a fatal error.
I back the values to default.
max_execution_time = 60
memory_limit = 128M
It did not work more :S
Downloading last version (1.6.7), Re-installing the program, doesn't work either.
What I can do? Thanxs!
