One more blank page

Just to keep this documented.
Installation went "ok", files in data/ have been created. Some of lock-files go from empty to lock and back while reloading. File permissions are ok, script seems to work, but there is only an empty HTTP 200 reply. Adding &login to the URL does not help.

After 2h debugging i found only two problems. In the installation guide is not mentioned that you need to create the photos/ dir. If you don´t do this the script will bail out at main.php:1064 without any hint. The second problem is that the line main.php:1063 theme_generate_error_page(); does not show anything (so no message at 1064). But i haven´t investigated that yet.

One remark: please don´t exit(0). Exit Code 0 means "OK", and the exits here aren´t clean.

Update:
Replacing include() with require() in engine.php:371 shows the problem:
Fatal error: require() [function.require]: Failed opening required 'themes/Borders/error.tpl.php' (include_path='/usr/local/php/lib/php') in /www/phpalbum/themes/engines/phptemplate/engine.php on line 371
-------
That´s the problem. A wrong inclusion path. Please replace include() with require(). I think that will help a lot. After fixing that, everything works.
