Hi Fellows, I'm getting this warning on my website: Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0 I don't really understand, how it comes to that error. In the php.ini is written, that this error occours when i register a session in a global scope. What does it mean exactly? Another thing is, that I'm often loosing the session, while surfing the website using ajax functionality in the background. I started to send the session id with the request all the time, but it seems, that some of the request are made, without showing an IP Adress in the sessions table, of my installation. I'm actually not using cookies, but the error does not occour in mozilla firefox on a windows plattform, its only occouring under linux using firefox. Internet Explorer isnt tested well enough yet, to come to an conclusion. Maybe someone is working with ajax, alot, so you might have experience with it too. Thank you very much for your help.
