Problem installing on local server: Chmod

1. OFC you can't change the permission using FTP client. It's a normal as a rule (I can't do it too with script-made folders/files that located on the server of my host provider). Maybe you would be more lucky if you try change the permission to target file/folder using hand-written php-script. The function is: chmod('url', 0777);

P.S. I can mistake...

IDK what file(s) exactly you should touch, but principle is simple. For example you wanna change permission of index.php (actually I recommend you to change permission of all of the files and folders in your FORUM catalogue). Your actions: create some *.php and put in there following code:

chmod('/forum/index.php', 0775)

Then run it. But I think it's a dead attempt.

P.S. What kind of host ground do you have? Virtual host or dedicated server?

Contact your host.

Also, 'Urgent' is absolutely useless as a thread title. Use a meaningful title next time.

No worries. It is just that it makes it harder for people to gauge what the thread is regarding.

Who is your host? That reply they gave you seems pretty much useless. You really need to try them again and try and get something useful out of them. If they are that useless again with their response, I'd suggest switching to a decent host, personally. You may get this specific problem sorted without their help eventually, but that type of offhand host will always cause you problems in some way or form

Create a new PHP with:

<?php
var_dump(chmod('./cache', 0777));
echo "<br />";
var_dump(chmod('./img/avatars', 0777));
?>

and save it on your PunBB root by the name of 'chmod.php', then use your browser to open it (once it's uploaded to your server).

You should see:

If not, something else is wrong...?
