PKP Bugzilla – Bug 6923
Maxlength of title fields set to 255
Last modified: 2013-10-29 23:04:10 PDT
Article titles are now (as of when?) stored in a 'text' (blob) column in database, but title fields are rendered to the user with their 'maxlength' attribute set to 255.
Text columns may contain up to 65,535 characters...<http://help.scibit.com/mascon/masconMySQL_Field_Types.html>
I don't actually think this has ever been a problem?
