I use the version 4.1.2, I have sent you a pn

Version 4.x accepts a maximum of 250 chars in any string passed to the server. This is the old behavior for http protocol.

Version 5.x has it to 1024 chars, that is the current behavior for http protocol.

You should upgrade to version 5.x and it will fix in the next google update.

Hi icefire

is it possible to edit the source code of the 4.1.2 version that the version accept longer referer strings too?

i have made a lot of mods for 4.1.2 for personal use, and i have the same problem, but i dont want to upgrade to Cjoverkill v5, because than i lose all my modifications.

would be nice if you can give us a solution ;)


i have found the following line in the in.php

Line 113 "if (strlen($referer)>256){"

i have edited 256 to 1256, and it worked for me, is it a real solution which works for every visitor of my website? that would be nice. does it take a security risk to set this value higher?

You can change the strlen value to 1024 or more. It's not a security problem for CjOverkill itself, but it may be a problem for other scripts you run. If it works for you, then it's ok.

hi :)

which problems could be faced on other scripts, if i change this value?

This value basically cuts the strings that are passed to your site.

For example, a buggy wp version would be protected to some extent from automated robots with that.

Of course, if your other scripts have no security bugs, then this is not a problem at all to be changed. In any case, in version 5.x it just cuts the strings to the maximum value the server should accept ignoring several automated bots that way, but nothing else.
