Hi Jack, I had already done in advance. The error is only occurs then, when new files are saved in the directory. Only i delete the referenzfile manual with FTP, I can create a sitemonitor new reference file. sitemonitor can not delete the old reference file itself. the permissions of all files from sitemonitor are 644.
I have install the latest version 2.9. the shop running under osCommerce Online Merchant v2.2 RC1, Server OS; Linux 2.6.28.8-20101130b-iscsi-ntacker-fasync-mremap-amd-sec6-grsec; MySQL 5.0.91-log; HTTP Server: Apache ; PHP Version: 5.2.17 (Zend: 2.2.0)
THX for your brainstorming ;-)
regards max
