Row size too large update error

I am trying to update my Joomdonation from 5.8.8 to 5.9.2 before the subscription expires and I'm getting the following error:
"Row size too large. The maximum row size for the used table type, not counting BLOBs, is 8126. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs
Package Update: There was an error installing an extension: com_jdonation.zip"

I would appreciate any help. Thanks.
 

Hi Igor,
The issue has cause from the limitation of your database. When you enable Joomla multilingual and add one language into your Joomla system, Joom Donation will create various db columns to store data of donor in new language.
But as i said before, your database has limitation so that you will have that error. Please reply the Ticket and we will help you to solve the problem.
Thanks
