Note: debug (using xdebug) has been working great on this machine for months.
Using aptana to debug php app on local machine (win7). Webserver is wamp. Was working fine earlier today, now when I come to step thru app (configured for external firefox browser), shows 1st line of app, session_start. Singlestep that, and firefox comes up with "Problem loading page, connection reset" and url in address bar changed to http://www.localhost.com/index.php?XDEBUG_SESSION_START=ECLIPSE_DBGP&KEY=12880228993397
Wtf is going on ? nothing changed. No local DNS changed on machine, NOD32 not installed, hosts file contains:
127.0.0.1 localhost
94.xxx.xx.xx teststats.mydomainhere.co.uk
94.xxx.xx.xx test.myotherdomainhere.co.uk
Can't think of what else to check. As I say, was absolutely fine earlier today, no changes to system config, hosts file, aptana config.
Also, if I set Aptana's browser to Chrome, it just bombs with connection refused.
