Theme development

It doesn't matter what template I try, but I get :

Fatal error: phptemplate_init(): Failed opening required '' (include_path='.:/usr/lib/php') in ./themes/engines/phptemplate/phptemplate.engine on line 55

with all installations of 4.6 on my local test computer. I do not have this problem with 4.6 before on my published site.

Whilst all works ook on my remote server, I've just returned to a fresh test installation of 4.6. and phptemplate, and I get this error with most themes, inc. my own custom, blix, freinds electric, blumarine, but not adc:
[code]Fatal error: phptemplate_init(): Failed opening required '' (include_path='.:/usr/lib/php') in ./themes/engines/phptemplate/phptemplate.engine on line 55[/code]

i've heard about the extra white space in php code, but this is happening with 'vanilla' downloads.
Cant understand it.

I found the search function doesn't work in non-standard themes like Blix and
Manji, but does in standard themes like bluemarine and friendselectric.

How can continue to work with on the non-standard theme I started on , but incorporate a working search function?

I checked page.tpl.php in Blix and in Manji, and they seem to have similar but not identical search function code as in the standard themes. I can see this is not a phptemplate/xtemplate issue.

I can't show the code here as posting won't allow it.

It seems these are default in Drupal through every theme - the triangles and squares used in the nav menu for collapsable and non-collapseable links.

I was wondering what I need to do to change this. I looked through/tinkered with the CSS, but I can't seem to find how to change them. I could just be missing something.

Any help is appreciated, thanks.

It gives me that error on the admin pages:

themes/greenmarinee/search.gif not found

I´ve searched for it, but didn´t found nothing. Any help would be appreciated. Ty!

Hello, I have a problem with the green marinee theme. The footer image is not where it must. It appears floating a little over the bottom. You can view it here: http://poquer1.com.

Anyone have idea of what can be the problem? Thank you, Simon.
