Notice: Undefined index: LBL_SEARCH in C:\xampp\htdocs\suitecrm\modules\ModuleBuilder\MB\MBLanguage.php on line
Often these “Notice” errors don’t make any difference.
Can you try editing that file and change the line that says
'LBL_SEARCH_FORM_TITLE'=>$mod_strings['LBL_SEARCH'] ." ". $this->label,
to something like
'LBL_SEARCH_FORM_TITLE'=>"Some text, ". $this->label,
and then try the custom module creation again? This is just a test to see if this error is making a real difference with your problem.
I’ve come across this post and modified the file as suggested and I’m no longer getting the error message the original poster is experiencing.
