Re-naming Admin creates php errors

[kuroi]

The warning that you quote above, usually tells you where this output is coming from, but seems to have been chopped off in your post.

Here are the errors messages with the sensitive data expunged:
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at ...shop/admin/includes/configure.php:183) in ...shop/includes/functions/sessions.php on line 108

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at .../shop/admin/includes/configure.php:183) in ...shop/includes/functions/sessions.php on line 108

Warning: Cannot modify header information - headers already sent by (output started at ...shop/admin/includes/configure.php:183) in.../shop/admin/includes/init_includes/init_templates.php on line 36

Line 183 in the configure.php document is after the closing ?>
It is a blank line. Could the blank line be causing the problem?

Thank you kuroi,
It was indeed a blank line at the end of the php code that was creating the problem.

The warning tells us that there is a problem at the end of your configure.php file (as you have confirmed). As the file is normally only half this length, the problem is probably due to a problem with the way in which the app which you are using to upload the file is configured. It's probably causing the file to be double-spaced by mishandling the invisible line end characters.

If your configure file has a closing php tag at the end ("?>") then the problem would be that this doubling up has resulting in there being a non-printing character output after that tag. In which case, counter-intuitive though it may sound, simply deleting the tag would also have resolved the problem for you. In general, it's a good idea nowadays to leave the final php closing tag off the end of files specifically to avoid the problem that you had.
