I downloaded the jemH plugin and when I click to configure I am getting the following error

This is a know issue due to an earlier install, the workaround used to date is to drop AO_78C957_LDAPCONF , it is a conflicting table I can't fix automatically. The change referred above may work, but I also have the identical problem in SQLServer, which does support foreign key constraints.

Hi Shamhoon,

Judging by this error message, it seems an issue related to database engine. This mesage usually occurs when the database is set to MyISAM, you may want to check this with this query:

show tables status;

In case you have tables using MyISAM, they need to be converted to INNODB. I found this KB article which has the instruction for this conversion.

I hope this has helped.

Cheers
