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:

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?

hello, i have already answered you via a PM :

the account you sent me is not super admin and i cannot check what it happening

Sorry, i changed it into Super Admin,

I sent a PM about but I did an error (I sent a pm to me) :oops:

I edited the phpThumb.config.php

Changed to

$PHPTHUMB_CONFIG = false;

Now I have an error message:

With files (images) that are not existing.

I will check that and come back.

I copy images from the old website to the uploads folder, and some pictures appear in the file manager.

But it seems that a lot of images still missing... I have the impression that only recently added pictures are present in the upload folder. During the successive version of Flexicontent, the way how were stored the images changed. I have reduces/cropped images but not sure that flexicontent was keeping original at the beginning...
