The text (your IP (ADMIN)) could/should be removed... Not entirely sure that is/would cause the warning. Basically what is happening is that as the code in that section is executed, one or the other side of strstr comparison is empty.. It could technically be either side, but I didn't think that $_SERVER['REMOTE_ADDR'] would likely be empty, but it is a possibility.

I believe (and hopefully someone else might confirm or deny this) that if the front text of the above is removed up to the first IP value (which yes, I understand is not a grouping of 0's as listed above) and the problem persists that it may be a server setup issue. I also haven't personally compared the above code with fresh install code to identify that all is as it should. Just troubleshooting what has been provided... :)
