it's a shared server (using cpanel you're right) and I don't seem to have access to this "my.cnf" ... where should be this file? ... I didn't find any with this naame

Thanks Fotis, I'll transmit to my hosting company. Usually they argue that it's a shared server son can't make any individual change ... but I hope they'll agree to do.
Have a nice day ... I'll inform if any progress for solution.

Hi Fotis,

The DB admin had a look and his answer is the following:


"The suggested variable is already ON:

mysql> show session variables like 'innodb_large_prefix';

+

---

+

---

+

| Variable_name | Value |

+

---

+

---

+

| innodb_large_prefix | ON |

+

---

+

---

1 row in set (0.00 sec)

Customer must create table with:

ROW_FORMAT=DYNAMIC

E.g.


CREATE TABLE <table_name> (

... field definitions ...

) ENGINE=InnoDB ROW_FORMAT=DYNAMIC;

This is a common issues when importing from MariaDB or MySQL > 5.6"

SO WHAT CAN I DO AT THIS STAGE?

Really embarrassed not to be able to use K2

OK thanks a lot!
I'll try to do so asap.
Hope it will work ...
Have a nice day.
Marc

done ... and works!

MANY THANKS FOTIS !!!!
