Fatal Error after copying new version

[bob_basli]

Hi,
my site was running on 1.4.1. Then I wanted to upgrade it to 1.5.2 but some modules didn't work after upgrade. So I downgraded tot 1.4.1 again. After few questions in the forum on how to work around this module I wanted to upgrade again to 1.5.2 but now, when I go to http://www.mysite.com/install/ipgrade.php I receive following fatal error:

Fatal error: Cannot redeclare redirect() (previously declared in /home/w6717389/domains/mekotrading.com/public_html/lib/misc.functions.php:32) in /home/w6717389/domains/mekotrading.com/public_html/lib/misc.functions.php on line 1688

What's happening and most important, how do I fix it?

Regards,
Arjan

Make sure your upload is OK with admin panel checksum or FileZilla folder comparison tool.

Sorry, but I don't get that fas.
As soon as I upload the new version, overwriting all extisting files with filezilla, I go to the link http://www.mysite.com/install/upgrade.php
Then this fatal error displays so I can't even check using the checksum.
When entering the admin this fatal error appears:

Fatal error: Cannot redeclare sanitize_get_var() (previously declared in /home/w6717389/domains/mekotrading.com/public_html/include.php:240) in /home/w6717389/domains/mekotrading.com/public_html/include.php on line 519

If you use filezilla, please try its folder comparison : it compares recursively local and remote directories. Hence you can compare an 1.5.2 unpacked on your local computer and what you are doing on the remote server.

I found an old backup and just completely restored the old backup (1.2.3) It was working fine so I just don't upgrade for now.

Hi I need to upgrade now anyhow.
I used a decompressed copy of 1.5.3 to ftp with filezilla. Selected the overwrite on all.
After entering the address: http://www.mysite.com/install/upgrade.php I get followin return:

Fatal error: Cannot redeclare cms_config_load() (previously declared in /home/w6717389/domains/mysite.com/public_html/lib/config.functions.php:31) in /home/w6717389/domains/mysite.com/public_html/lib/config.functions.php on line 495

After this I am not able to logon to my admin and need to re-copy my old site again!
Who can help me out.

Btw: I'm trying to upgrade from 1.1 to 1.5.3.
