soluction
This problem can occur if you are using cpanel terminal or SSH to export databases using mysqldump.
Command you probably use:
mysqldump -u [username] -p [database] > dump.sql
The Problem that occured:
mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces
Solution:
add this parameter: --no-tablespaces
sample:
mysqldump --no-tablespaces -u [username] -p [database] > dump.sql
