TC not accessible after update

ok thanks
so if the tables are empty, the problem can not be related to the data stored into the database
was TC already installed on this website before you install the V5 ?

Please send me an admin access + FTP access by email. I will check that, but only next week

Yes, TC was already installed and in use.
I send your credentials by email.
Thank you!

thanks for the access, as said by email :
I have located the problem during an update of the database to add a column and this could be related to the strict mode of InnoDB
I have included the column in the install sql file to avoid the problem. This fix will be included in the next version

Thank you, Ced.
I'll wait for the new version of TC to upgrade it on all my sites.
Thank you again
