WordPress .htaccess file breaks webdav

Have a look at Jeffrey Harrell’s plugin. Although its for enabling iCal calendar publishing, it should help with any WebDAV application.

I had found that, but didn’t know if it would work. However, trying to upload it gives me:

Incompatible archive PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

That is downloading directly from that site. I can try installing the php file (inside the .tar.gz file) directly, but since it says WordPress 2.1+ I am a little hesitant.

OK, went ahead and installed it anyway. It does nothing to the .htaccess file at all, even after going in and saving a post (Updating). I looked at the code and it looked like the line it was adding was, essentially, this:

RewriteCond %{REQUEST_URI} !^/(‘wp-content’)

(there were more things in the ” in the default script)

but adding that line into the .htaccess manually didn’t seem to have any affect.

.htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/(‘wp-content’)
RewriteRule . /index.php [L]
RewriteRule ^u/([0-9]+)$ wp-content/plugins/short-url-plugin/u.php?$1|$2
</IfModule>
##EOF

I solved this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{HTTP_HOST} !^webdav
RewriteRule . /index.php [L]
RewriteRule ^u/([0-9]+)$ wp-content/plugins/short-url-plugin/u.php?$1|$2
</IfModule>

My webdav is setup as https://webdav.example.com/ so the various REQUEST_URI variations simply didn’t work.

The trouble now is how to make sure that that line stays in. For now, I am making the htaccess file owned by root so that WordPress cannot alter it. Not ideal, I know.
