[pmwiki-users] Anyone recognize these error messages?

[Tegan Dowling]

I just tried to install my usual pmwiki template site (v 2.1.26) on a
friend's hosting account, using a hosting provider I'm not familiar
with.  This is why I usually just stick with what I know works --
because I don't actually understand *how* it works, or fails to do so.

I installed on www.theirsitename.com/test/, and the top of
www.theirsitename.com/test/Main/HomePage starts with the errors below
- followed by many more, among them the usual

"Warning: Cannot modify header information - headers already sent by
(output started at /home/justice4/public_html/test/pmwiki.php:281) in
/home/justice4/public_html/test/pmwiki.php on line 884".

I'm about to just give up, but thought I'd check here first -- does
anyone recognize these, and maybe know if the problem is with some
server variable or some such?  I don't know much about the
environment, other than it's hosted with https://www.2mhost.com, and
cpanel says: Apache version 2.2.6 (Unix); PHP version 5.2.5.

One possibly useful factoid (I don't know, since I don't know how this
works):  I had to change pmwiki's root-level .htaccess file to

RewriteEngine on
RewriteRule ^([A-Z].*) index.php?n=$1 [L,qsappend]
RewriteRule ^$ index.php [L,qsappend]

from the one I usually use:

RewriteEngine on
RewriteRule ^([A-Z].*) /index.php?n=$1 [L,qsappend]
RewriteRule ^$ /index.php [L,qsappend]

Until I made that change, I got 404 errors.

Here are the first of the errors I do still get -- thanks for any
suggestions (other than to just hang it up! :) )
