Tody i have succesfully installed sobipro component in master site but suddenly when i have to installed sobipro component in slave site so this error has occure


500 - An error has occurred.
JDatabaseMySQLi::query: 1061 - Duplicate key name 'uniquePermission' SQL=ALTER TABLE `sea_sobipro_permissions` ADD UNIQUE `uniquePermission` (`subject`, `action`, `value`, `site`);

This error seems coming from the SOBI Pro content that would have duplicate value inside the table. So that the alter table that seems to be executed (perhaps during an update/upgrade) cause the error.

Perhaps that you should report this issue to Sobi Pro and that can help you identifying what in their "permission" is duplicated.
OR use PHPMyAdmin and try identifying the duplicated record to idneitfy the origin of the problem.
