Sorry, i am not a developer...more of a user. i havve been getting this error
Cannot write database session - please verify max_allowed_packet is at least 4M!
while working on Moodle, usually in editing mode. It is inconsistent. The next minute it will work for 3 to 4 hours then when I clicked on the 'configure' button to edit a section or clicked the Save button to save a section or activity, the error popped up again.
Can anybody advise pls. Thank you.
