PHP 4.0.6 file upload problems?

Hello all! Some of you know, some of you don't know that I'm the maintainer of a GNU PHP groupware project - http://outreach.sourceforge.net (the project name is OPT) - sorry, couldn't help advertising :-). One of the users of OPT has major problems uploading files to the system and I have absolutely no clue why that is. His PHP version is 4.0.6 on Linux. Quoting his description of the problem: "In fact, now it doesn't even report an error. It just takes some time (about 30 seconds) trying to upload, I guess. The progress bar in the bottom of MSIE 6.0 shows it doing something, but then it 'finishes', while still showing the page with the 'Add a new document' form." I know, your first thought is that OPT has a problem - but here's another report from the same user when I directed him to alter some stuff in a MySQL database: "By pasting it into the 'query' window in phpMyAdmin, but I was surprised by the result. Instead of an error or successful result from phpMyAdmin, I got a browser error from MSIE: 'This page cannot be displayed'" I have absolutely no idea why this happens - when he sent the first report, I started thinking it may have been some php.ini setting regarding uploads, but I was completely confused by the second report. Did anyone encounter this? Is it a PHP bug? Is it a setting? Thank you, and I'm sure Tom will as well if you can help us here! Bogdan Stancescu
