Hello,

We will advise how you can achieve this.

Basically, at this moment, if you have already set that column to be a "one-line string" when it was created and you need to increase the character limit for it, there are two ways how you can do this :

1. You can go to your database using something like PhPMyAdmin or any other DB management Tool:

I will show you a guide how you can change the character limit of the column(s) in your Database directly, without losing any data from that Column :

 For example, if you got a Manual or SQL Query Table, you can do this :

Enable editing for a moment and check this box, here you will see "MySQL table name for editing" :

Then, in phpMyAdmin ( or any other Database Management Tool), go to your Database, find the table, click on the "columns", find the Column you need and go to "change" button :

and change from VARCHAR to TEXT as shown.

The differcence is - a column from VARCHAR type( which has a limitation of 255 characters) will change to TEXT type( 65,535 character limit) ,

so then you can save the change and when you go back in our Plugin's table, you will be able to write any text you need in the cell.

2. - Or another way ( this one is only for Manual Tables) - you can delete and recreate this column in the Manual wpDataTable and set it right away to be a "multi-line string", this way you will ensure that it has this much higher character limit when it gets set in the Database as "TEXT".

Let me know how it goes, and if you need further assistance, please. Thanks.
