I was trying to customize some of the language in the file and edited the sample-custom.php and renamed the file en-custom.php. The edits are working but I'm getting the below error in my header: WARNING: Cannot modify header information - headers already sent by (output started at /home/content/r/m/s/rmsaamweb/html/amember/language/en-custom.php:17) in line 1623 of file common.inc.php Do I need to edit another file? Thanks!
