Thank You Alex,
But, I don't need a page that every user will see , it's like suspension.
I need a little code that will appear on every website. I saw it in some free hosting website, they got automatic adverts.
Do you really need it for the time you're going to update your software? It's not a question of 5 minutes to make it to work.
I've done in some time ago, but I have no guides, so you'd better search the forums, as it was already discussed here, or use Google.
nope, I need a to put a link to a thread that warns about a server upgrade,
I already tried to do it via php.ini and httpd from someone's help, but it caused lots of errors and open_basedir things, had to put it down for now.
I did actually Google'd, but it didn't showed nothing [ maybe cause I wrote it wrong =/ ]
The simplest way, as I see it (somebody else might see it another way), is to setup a front-end to Apache (e.g. nginx, lighttpd, squid, opps, etc) and add your HTML with its help.
