Solved Transfer problem with kunena_aliases table

Hi,
I has to transfer a website with J!5 and Kunena from my hosting to an other. It's the same host, but different account. I created a backup with Akeeba and tried to install it on the new host but the database install blocked because the index of the kunena_aliases table is too long. I skipped this table and the install finished correctly. I tried to install this table manually but I receive the same error. I changed the varchar of the first field and then I can import it. But I can’t put the varchar back to its original 255. I don't have problem on the source database, I can put the varchar in its original configuration. I don't understand. Same host, same mysql version. How can I impor this table without error ?

Thanks for your help

This value 255 must still be from previous installations.  On my test pages I have the value varchar 250 everywhere.
But this was also changed again at some point, as the value varchar 191 is entered now for a new installation. github.com/Kunena/Kunena-Forum/blob/691f...e_tables.utf8.sql#L3
So this lower value should not cause any problems.

Thanks a lot !
I will do that.
