If everything is working as expected on all sites, so, the issue in first import on your server. But I can't fix this. Why do not remove all products and import them correctly? I am sure that first import was run wrongly or you simply deleted some custom meta when you make server update. 

New plugin will be released on this week and you can try it, maybe it will help

Hello, 

Finally, can we find a solusion?

Hi 

You can see the problem only in my server.

Please, check my problem because I have a thousand products to import and i am not able to go on due to this problem.

Thanks

Just write me how I can reproduce your problem on my test server. What
should I do to see problem?

Hi 

 The settings are same both for first import and new import. After many tests I realize that we can solve the problem only if we re-run the first import (WPallImport) and then make a new import. But the first products are too many to re-run them.

There is no problem with the new imports.

I insist, because it's the second time that i update server and i have the same problem.

I beleve that something happens during the servers change  the plugin can't recognaise the  '_ce_unique_pid' from first imports.

Thanks

Server update doesn't affect import. Maybe you made first import with wrong
settings. Please, describe how to reproduce your issue on new site or with
new imports, do you have problem with it?

Files which you use for tests

Hi,

Which files the test.xml?

The problem is only in the site where I changed server.

In an other test site where i make test it works fine 

Thank You

just send me your files

send me please some urls or files which you used for testing. We will test
them on updated plugin

currently I can't check this as we don't want to check old addons. We will introduce new soon and then you will be able to retest this and send access to our developers for investigations

Currently, you are using our old addons, its not supported. You can
download actual from Rehub - plugins. But better to wait our updated import
plugin

Hi 

Did you check my problem?

I dont see that you have common post id. But, ok, more easy if you send me
admin access

Send me screenshots of import settings for first import

Your first import added regular WooCommerce product. I dont see in your
screenshots that you added Content egg offers in first import. Also i don't
see that you use content egg product layouts. Please, enable them first.

I have used the same scenario "http://rehubdocs.wpsoul.com/docs/rehub-theme/affiliate-settings/bulk-import-of-offers/#Content_Egg_addon_for_bulk_import_and_price_Comparison" Where is the differend?

You are trying to use Content Egg for SKU, this is not working. If you use Content Egg, you must use methods for Content Egg. SKU and Content Egg are different things and different scenarios

This is way to use Content Egg

http://rehubdocs.wpsoul.com/docs/rehub-theme/affiliate-settings/bulk-import-of-offers/#Content_Egg_addon_for_bulk_import_and_price_Comparison

Hi. You missed to send us screenshots of all your settings and actions

When importing new products the Content Egg plugin deletes the previous offers and introduces the new offers with the same '_ce_unique_pid'.

And this happens when there are many stores in the previous offers, it deletes them all and you only keep the last one imported.

Import products : WP All Import

mode of importation : Existing Items 

Record Matching: _ce_unique_pid => {part_number[1]}

Thank You.
