no, you dont understand me.
I changed storage engine from MyISAM to InnoDB for all _comprofiler tables, thats alright, but i still cant add new field in joomla.
But when I click on operation tab in phpmyadmin, its shows me a warning:
PhpMyAdmin configuration storage has been deactivated.
But i am not sure, what it means.
I ask my host provider if mysql database is running correctly, because in status is, that mysql server is running just a 5 days, but my web has two months, so maybe he made any restart or sometnihg else? I will write back.
For now very thanks.
