MySQL: error 1118 (42000) row size too large
Sounds like the import forced the Engine to be InnoDB??

If so, then let's see the my.cnf and figure out what to fix.

If not, then let's see the CREATE TABLE that is leading to the problem.

Or, maybe, a CHARACTER SET default changed.

Show us the first part of the dump and the CREATE TABLE just before the naughty table.
