Hi,

Ok, I found in which tables I got this problem.
This is problem is from tables: messages and messages_text.
If I insert standard messages, messages_text tables is working perfect.
So the main problem is inside this two tables.

And I found one more problem:
If I use my table topics and after that try to create a new topic - there is a problem which told me that I didn't insert name for topic.
And if I use the standard topics table everything goes perfect.

So do you know how can I fix this two problems regarding my messages, messages_text and topics tables, because this tables contains all my data?

Ok, I found the solution.
There was a problem with Unique ID, duplicate it.

Here is the solution:

"This table does not contain a unique column. Grid edit, checkbox, Edit, Copy and Delete features are not available."

There are several working solutions depending on your exact scenario.

For example, as long as all of your AI or Unique identifier field are unique then you can simply alter the table and ensure this is the Primary key and set to unique value.

I solved this with this solution on one of my tables.

The other table had multiple AI int values that were the Primary field, but there were multiple values of the same kind.

The simple fix for this was to just add a column to the end of the table as Unique AI Int. Basically all MySQL is saying is it needs a unique value in each record to differentiate the rows.
