Moved to a LINUX server and admin page comes up blank

[bulpup]

I have going thorugh everything I can find on the issue of moving from one server to another. I used the document oulining how to do the migration and everything went smoothly.

Of note, The new installation to the linux server went as easy as this doc outlined:
http://www.zen-cart.com/content.php?...fferent-server


The installation was checked and I logged into the admin and catalog area. After uploading the old files, importing the SQL and running "fix_Cache_key" the website's main area was displayed in Maintenance mode as was the plan. THe admin area, however, comes up as a blank page. I went through the following page:

http://www.zen-cart.com/content.php?...working-for-me

and the only outstanding thing was that there were https: in the ssl urls but that the enable SSL was set to false. none of the suggestions from the above page seemed to help.
I did notice that there is no"Sessions" line anywhere in my admin>includes>configure.php
Also, I have an htaccess file on my pc but when I upload it to the site it accepts it then disapears.

It seems to me this is not a session issue but I can't really find anything wrong in my configs files either. Any help would be appreciated because just today the site actually got some unexpected press but I am currently down.

Post both of your configure.php file contents here - x'ing out the db details

Here's the RAW "dist_configure.php" file for admin/includes...

Does yours contain all the defines?

Your subject line says "admin page comes up blank". But you've not posted what errors are being logged. http://www.zen-cart.com/content.php?124-blank-page

Ah, I hadn't seen that page. Good info there. I have the logs and the warnings are of the "headers are already sent" variety.

I am going to go through that page's suggestions before I post any more info. I will let you know how it ends up.

oy The first log started with this.

[01-Apr-2013 15:37:33] PHP Warning:  session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cookie - headers already sent by (output started at /home/xxxxxxxx/xxx/xxx/xxx/web/MYSTORE/MYNEWADMIN/includes/classes/logger.php:127) in /home/xxxxxxxx/xxx/xxx/xxx/web/MYSTORE//includes/functions/sessions.php on line 113

the logger.php file had two lines after the ?> I fixed that, then each subsequent error log started with another .php file in the /MYNEWADMIN/includes/classes/ directory.
I have since gone through each and every file in that directory and removed extra lines at the end.

Well now the new error logs report this.

[01-Apr-2013 18:23:43] PHP Warning:  session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cookie - headers already sent by (output started at /home/xxxxxxxx/xxx/xxx/xxx/web/MYSTORE/MYNEWADMIN/includes/extra_datafiles/music_type_database_names.php:49) in /home/xxxxxxxx/xxx/xxx/xxx/web/MYSTORE/includes/functions/sessions.php on line 113

So, painful as it sounds, it appears my old server had no issue with my files having spaces at the end of the php code and my new one does. From the looks of it, all of my files will need to be changed. Is there any other fix that you can think of that would be a swifter resolution?

Sounds like whatever process you used to transfer files between servers has mangled the line-endings on all your files.

You'll need to clean them up one-by-one.

Usually when that happens, I go to the copy on my PC instead, and copy those up to the server. Of course, this assumes that the files on my PC already contain all the customizations that my server files contain. This is where reliable backups are important. So is a good FTP program.

Yea. 56 and counting. Random and all over the place. This was all done via Filezilla, which I find pretty reliable. Although, come to think of it, the connection was rather flaky during the download. Timeouts and retries but no failures.

That must have been where it happened.
