Can’t update WordFence Options, clear data manually

I found a post on Stack Overflow advising that converting a column from blob to text should result in no data loss. I didn’t really care about data loss since I wanted to remove the plugin data anyway, so I gave it a shot.

On the Structure tab in phpMyAdmin, I edited the val column and changed it to text. Then I found the option for deleteTablesOnDeact and changed the value from 0 to 1.

After doing this, I was able to deactivate the plugin and the tables were all removed.
