Memory Limit (Installation)

I am currently switching from phpmyvisites to piwik. On the install page “system check” under optional, memory limit, it has listed ?M instead of 128M. The installation completed successfully (although as I was being redirected to login page from setup page there were 2 error boxes that flashed up and I didn’t get to see what they were). I’m just wondering if the ?M will interfere with piwik’s ability to record all stats properly (doesn’t seem to be so far). I am running Windows 2000 server, Apache 2.0, PHP 5.1.4. Thanks.

Just a quick update, after installing successfully there is a slight issue: When I click a button (any button, Dashboard, Visitors, etc.) it says “Oops… problem during the request, please try again.” in Orange, then fades and the data doesn’t display. I just have to click again, and it displays fine.

I searched for this and found someone with same problem, looked like memory issue. I increased memory to 128, and the error does not display as frequently, but it has not completely gone away. So I used:
max_execution_time = 3600 ; Max execution time of each script, in seconds
max_input_time = 120 ; Max amount of time each script may spend parsing request data
memory_limit = 512M ; Max amount of memory a script may consume (128MB)
And I am still getting the error every other 4 clicks or so. I would like to check the error logs but, being a complete noob, I cannot locate them style_emoticons/<#EMO_DIR#>/blink.gif

Any suggestions or comments would be greatly appreciated. Thanks.

The error seems unrelated. Do you get it on http://piwik.org/demo ?
