pleas help warning errors message after install mod

Hello Everyone,

Can someone help me please, tell me what to do.

I just install this mod and have this error

from front end after login as member, click on "petition" I got below error message

Warning: Cannot modify header information - headers already sent by (output started at /home/guitar/public_html/modules/modzzz/petitions/classes/fpdf.php:3465) in /home/guitar/public_html/inc/design.inc.php on line 133

from adminmodules/petition -  I got below error message

Warning: Cannot modify header information - headers already sent by (output started at /home/guitar/public_html/modules/modzzz/petitions/classes/fpdf.php:3465) in /home/guitar/public_html/inc/admin_design.inc.php on line 56

thank you

This error is usually attributed to extra lines at the end of the file (after the ?>). I'd check the file giving the error to see if this is the case.

i went to cpanel of the site, click on file manager and edit the design.inc.php

i went to the end of the file, i see the cursor is right underneath the ?> so i bring the cursor up liked this ?>_

i then hit delete key on the keyboard to make sure nothing left then save.

go to admin clear caches and everything, i still see the errors

thanks

You're not looking at the file causing the problem. You should be looking at /modules/modzzz/petitions/classes/fpdf.php.

Thank you boss, that just to let you know how confuse I am, I am just trying my head of learning

thank so lot. I check that file now

Thank you so much it works. I felt so dump and stupid.  Thank you for teaching me how to look for which file in errors and fix that file but not others LOL.

still learning. THANKS

Good to hear. And don't worry about making a mistake or being confused now and then.

It took me years to realize you could create a join form with multiple pages.
