I get an error from plugin "photo_added_by". It didn't show any info at all until I switched settings to "created at" from "author" ... now I get an error:
"Notice: Undefined index: Photo_add_by_show in /home/www/photographie/plugins/Photo_add_by/initpicture.php on line 70
Warning: Cannot modify header information - headers already sent by (output started at /home/www/photographie/plugins/Photo_add_by/initpicture.php:70) in /home/www/photographie/include/page_header.php on line 101"

about hiding Notices [Forum, post 166459 by flop25 in topic 27628] How to disable high resolution? : those are not errors just notices
But I notify the author that he probably forgot a detail to get a perfect clean code.
I thinks you've update manually plugin ?
desactivate, activate plugin
