apache won't restart after defining xdebug

[teptwep]

hello,

i'm using the latest version of xampp (XAMPP 1.7.1) on windows xp, and when i uncomment the lines to enable xdebug, apache refuses to start.

implicit_flush = On

[XDebug]
;; Only Zend OR (!) XDebug
zend_extension_ts="C:\xampp\php\ext\php_xdebug.dll"
xdebug.remote_enable=true
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.profiler_enable=1
xdebug.profiler_output_dir="C:\xampp\tmp"


The forum search doesn't seem to work (Sorry but you cannot use search at this time. Please try again in a few minutes.)

just checked xampp\apache\logs\error.log

i'm getting this message

PHP Fatal error: [Zend Optimizer] Zend Optimizer 3.3.3 is incompatible with Xdebug 2.0.4 in Unknown on line 0

removed the other "zend_extension_ts=" statement, that made it work
