Test returning blank pages
Hello,

I'm trying to setup a private instance to work with IE. I have the server installed on CentOS and can access it via a browser. The agent is a Windows 7 machine. UrlBlast is running at startup. Everytime I run a test it returns a blank white page. I notice that the tests are being queued because I see "13 pending tests" next to test location on the webpage. I see all of the jobs in the work/jobs/IE/ directory. Thanks for any help you can provide!

**urlBlast.ini**
[Configuration]
Startup Delay=30
Log File=c:\webpagetest\agent\log\
Timeout=120
use current account=1

; Where to get work from
Url Files Url=http://www.mydomain.com/work/
Location=IE
Location Key=TestKey123

**locations.ini**

[locations]
1=Test_loc
2=Public_Dulles
default=Test_loc

[Test_loc]
1=IE
2=Test
label=Test Location

[Public_Dulles]
1=WPT_Dulles_IE8
label="WebPagetest.org - Dulles, VA"

[IE]
browser=IE 8
latency=0
label="Test Location - IE 8"
;browserExe=pagetest.exe
key=TestKey123

[Test]
browser=Chrome,Firefox
label="Test Location"

[WPT_Dulles_IE8]
browser=IE 8

RE: Test returning blank pages
Sorry, sounds like there are 2 different issues going on:

1 - The blank white screen. You should be redirected to a test progress screen, not a blank page. This does sound a lot like what mwhite was seeing here: http://www.webpagetest.org/forums/showth...p?tid=6181 (basically, zlib is a dependency that was not documented).

2 - The test agent isn't picking up the work. Check your access log on the server to make sure you see requests coming in from the agent for /work/getwork.php

Adding zlib worked! I now get to a screen that says "Waiting behind 17 other tests" but that number never changes. I went into /var/www/webpagetest/work/jobs/IE/ and removed the 16 previous entries and restarted Apache but nothing changed. It still says waiting behind 17 other tests. Any idea how to fix that?

Thank you so much!

RE: Test returning blank pages
The tests not running is a result of #2. It doesn't sound like the test agent is successfully communicating with the server. First step is to check the server's access log to see if the agent requests for /work/getwork.php are showing up (my guess is that they are not).

You can add "debug=1" to the urlblast.ini which will spew debug information to the log file that may help but ig I had to guess I would say that something is wrong connecting to http://www.mydomain.com/ from the test agent (that needs to be the server name that is running WebPagetest and it needs to be reachable from the test agent).

When you say access log do you mean /var/log/httpd/access_log? If so, that log is not showing anything regarding getwork.php.

I added debug=1 and rebooted the Windows machine. Don't see anything useful in the urlblast.log.

Sorry, is their anything else I could provide that would be useful in helping me troubleshoot?

RE: Test returning blank pages
Do you see the request URLs in the urlblast log? If so, can you try loading it up in a browser on the test machine?

Can you access http://www.mydomain.com/ from the test agent? If so, do you get the WebPagetest test screen?

I can access it from the test agent and I do get the Webpagetest screen. When I enter a URL and click test it says "Waiting behind 20 other tests..."

Here is what the urlblast log has:

RE: Test returning blank pages
Hmm, looks like it isn't starting up correctly. Try disabling UAC and make sure you are running it under an Administrator account. I'll see if I can figure out what the next step in the startup is supposed to be and what might be stopping it from working.

Thanks - I double checked and I am an Admin, UAC and Windows Firewall are disabled. I appreciate your help!
