Moving Wordpress site from Linux to Windows throws errors

Question

I've been asked to move someone's blog from a Linux server to a Windows 2008 box. I used Xampp on the new box. When I try to access the blog I get the following errors:

Any ideas?

They're _warnings_, not errors. They were probably there on the Linux box, but suppressed. In the short term, turn off warnings and it may all work. Your new PHP environment may be more recent, and so the warnings may cause more of an issue, so you may have to downgrade the version of PHP you're running (do this as a last resort however). Also, let the owner know, so they can get a PHP developer to fix them. — halfer, Aug 03 '12 at 10:50
You apparently run a *very old* version of Wordpress and should consider upgrading it. — fdomig, Aug 03 '12 at 10:54
cool thanks halfer, although i cant see the html for the homepage of the wordpress blog, im browsing on localhost to the index.php file in httdocs. i presume this should be the homepage for the wordpress blog? — user1238321, Aug 03 '12 at 10:57

I think your php.ini in your linux server was desactivating errors reporting.

For the strict standards you can hide them by removing E_STRICT from the option error_reporting in you php.ini file (but it may be better to fix them).

for the rest of the issues I do recommand you to fix them, especialy the warnings.

Also check that the PHP version in linux is the same as in windows, migrating from a version to another may result in issues like this.

check the used php-version on the server and on the xammp-box. You can do this with creating a single file that contains the single line

<?php phpinfo(); ?>

This gives you the used versions. If you can use the same versions on old and new system you can get less warnings, perhaps...

And if there are still the warnings, you can filter them out with the right entries in the php.ini.

if the versions are different do i have the option to downgrade the version in xampp? – user1238321 Aug 03 '12 at 11:07
5.1.6 old site - 5.4.4 new site – user1238321 Aug 03 '12 at 11:21
yes, you can find for sure an old version of PHP (Google will tell you where), or update Wordpress to an up-to-date-version that is compatible with the current PHP. If this site is just a private little system not accessible in public then the downgrading of the PHP is probably the faster solution. – lars k. Aug 03 '12 at 11:41
[This link here](http://stackoverflow.com/questions/1302168/using-xampp-how-do-i-swap-out-php-5-3-for-php-5-2) shows you how to change the version. Now you just have to find the old version somewhere. :) – lars k. Aug 03 '12 at 11:44

it is recommended for a productive system to not display errors, someone could use the information to hack your system... you can change the detail level of displaying errors as mentioned by Yazmat, or turn off the displaying of errors in php.ini like this:

display_errors = 0
