I just installed the new version of joomla 2.5 and the thumbnail does not display. I can see the thumbnaisl in the cache but I cannot see them on the site.
All works fine before I updgrade to 2.5
How can I address it?
I try many things but nothing work.
I verify the permissions and the owner also. All seems correct.
Where can I work for that. I use the template beez that's very simple.
I also use the admin tools pro but the settings work fine before 2.5.

Please help me . I have a problem with all videos pro plugin also.

I reinstall my site from ground to joomla 2.5.
I try to use the simple image gallery pro plugin in a new element in K2 and in the frontend I do not see the thumb at all.
I a blank rectangular and when I click on it I can see the picture.
How can I correct that?

Have you any idea about a solution?

I assume that you have solved your issue, cause the thumbnails display just fine...

Yes sorry, I correct the problem this night. I made two changes in an extension (AdminTools Pro) .
