This is the error when I want to change my default theme after 1.5 update :

OW Debug - ExceptionMessage:SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'graphite' for key 'name'File:/homez.615/camikas/www/ow_core/database.phpLine:331Trace:#0 /homez.615/camikas/www/ow_core/database.php(331): PDOStatement->execute() #1 /homez.615/camikas/www/ow_core/database.php(564): OW_Database->execute('INSERT INTO `ow...', Array) #2 /homez.615/camikas/www/ow_core/database.php(601): OW_Database->insert('INSERT INTO `ow...', Array) #3 /homez.615/camikas/www/ow_core/base_dao.php(215): OW_Database->insertObject('ow_base_theme', Object(BOL_Theme)) #4 /homez.615/camikas/www/ow_system_plugins/base/bol/theme_service.php(189): OW_BaseDao->save(Object(BOL_Theme)) #5 /homez.615/camikas/www/ow_system_plugins/admin/controllers/themes.php(79): BOL_ThemeService->updateThemeList() #6 [internal function]: ADMIN_CTRL_Themes->chooseTheme(Array) #7 /homez.615/camikas/www/ow_core/request_handler.php(266): ReflectionMethod->invokeArgs(Object(ADMIN_CTRL_Themes), Array) #8 /homez.615/camikas/www/ow_core/application.php(317): OW_RequestHandler->dispatch() #9 /homez.615/camikas/www/index.php(65): OW_Application->handleRequest() #10 {main}Type:PDOException
