I had this error message in mySQL during a database import. The dump was exported from another db server:

#1118 - Row size too large (> 8126). Changing some columns to TEXT or BLOB may help. In current row format, BLOB prefix of 0 bytes is stored inline.

On this machine I’m currently using MAMP on a Mac (Not the PRO version), but I think you can try to use the same config file in other versions.

This is what I did to solve the problem:

  1. I stopped the server in MAMP
  2. Inside the folder: /Applications/MAMP/config/ I created a file config my.cnf. I used the template file my-default.cnf that I found in /Applications/MAMP/Library/support-files/.
  3. The following is the my.cnf file where I added also => innodb_strict_mode = 0
# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

innodb_strict_mode = 0
