problem with phpThumb

After a successful migration, I have a problem with my images.
In the back-end I have an error as shown in the attached image:
[attachment=0:smh0zucm]<!-- ia0 -->Screen Shot 2012-10-24 at 09.23.24.png<!-- ia0 -->[/attachment:smh0zucm]
I guess that I have problem with folder access right or something similar... I was not able to have more details about the error.

I have this Notice
Notice: Undefined variable: img_assign_link in /250gb/extranet/administrator/components/com_flexicontent/views/filemanager/tmpl/default.php on line 371

When I am editing a record with a picture I have:

Notice
Image field: 'name of the field', some values of this field have been skipped because the original file seems to habe been deleted (thumbnailing of it has failed). This message will go away once you save this content item

yes .. you need to repuload your orignial images ... in upload folder

the images are there right?
something is wrong with the folder path,

i am curious why this happened, did you change the MEDIA folder path in GLOBAL configuration

you can send me a PM with admin login

all the website changed from www.wikilex.eu/extranet2011/
to www.wikilex.eu/extranet/
and I am not on the root.

I am PM you the login

Any news?
