Thumbnails problem

[Dunne]

Hello,

after updating Joomla 3.4.1 I have problem with Thumbnails. Sadently I can not see small thumbnails.
On ftp i can see that they are created even I recreate them I cant not see them only big ones.
In component I found all picture Image Filename does not exist, even I upload them once more small thumbnails don't work.

Setting for additional thumbnails is Medium & small.

Please let me know how to deal with this problem.

Thank you
Best Regards
Michaela

Hi, where they are missing, in administration or on site - in frontend?
