Hi, here some information about my installation:
DEBUG mode activated
'REPORT_ALL_ERRORS' and 'DISPLAY ERRORS' are enabled
All permissions are correctly set
1. EPESI version 1.5.4 rev11060
2. CentOS 6.4/PHP 5.3.26/MySQL 5.1.70
3. Shared hosting
4. I can not access directly the main php.ini file, but if needs, system administrator can edit for me.
The problem doesn't make log error, it is caused by the RoundCube module. It seems that once the module is installed and enabled there is an issue with it.
There is also another problem maybe connected to the above. When I configure email accounts the application doesn't make "EPESI archive" and "EPESI archive sent" folders.
Thank you.
Massimo
