[SIGPLUS_EXCEPTION_CASE_MISMATCH] Image source root/images/GALERIE/User/Arek cannot be found with a case-sensitive search but a file system entry root/images/GALERIE/USER/Arek exists. While some operating systems (e.g. Windows) are case-insensitive, others (e.g. Linux) are case-sensitive in matching file system entries. On this server, the image source must match the file system entry exactly, including character case.
