Um... Try upgrading PHP to 4.3.11

Also, make sure that if you have FastCGI enabled that you set "cgi.fix_pathinfo = 1" in your php.ini file.

check your config file, this sounds like you got a huge blank space at the end of it, causing the premature end of headers error. remove it, save the file and try again :)

Solved this sucker!

Post by adaptr »

I figured it out after a quick look on the ereg_replace manual page ;-)

The first offending line (43) is:

Code: Select all

$config["base_path"] = ereg_replace("(.*)[\/\\]include", "\\1", dirname(__FILE__));
which the manual says means that the \\1 will be replaced with the first bit between (), i.e. anything before the "include" part.
BUT - cacti thinks to be smart and figure out for itself whether it is running on WinDOS ( \ path separator) or Unix ( / path separator).


Needless to say, this fails - miserably.

If you read the above, you'll see that ereg_replace is apt to get confused by this - does he (that's you) want a string with "number" \\], or does he want an actual escaped backslash (\\)?

My guess is it tries the former, and gives up ;-)
If this is a parsing error then it's an actual PHP bug.

I solved it by removing the [] and the separator that is not for my platform (Linux), and voila - glorious install screens are here!


In case this much code confuses you, here's the new line:

Code: Select all

$config["base_path"] = ereg_replace("(.*)\/include", "\\1", dirname(__FILE__));
Note that this only works on Linux!
For WinDOS you'll have to use \\ instead of \/

Modify the second line(with the /lib path) in the same way.

Um....

If this was a problem, more people would report it. I think it's related to your version of php.

Sure, like a Linux system consists of a few, small, known-state parts ;-)

And an EDIT: that's actually pretty insulting to the OP of this thread: he reported this problem.
Now you're saying it must be my problem ?

Well duh - that's why I said it may be a PHP bug.

I'm running php 4.3.11, by the way - the version you repeatedly recommend to upgrade to.
