{{header_en|title=Some VtigerCRM common errors and their solutions| keyword={{Template:keyword_en_vtigercrm}}| description=A selection of common VtigerCRM errors and the respective solutions | link_page=vtigercrm_errori}}
As a custom module developer for the '''VtigerCRM''' software I incurred in some errors while writing code; my goal here is to describe them as best as possible. I'll provide a brief description for each error: the error message, if available, and the solution to the problem. I'll try to provide even links to the project documentation when needs be.
As a general rule to problem solving I'll suggest to set '''Php''' parameter '''error_reporting''' equal to '''E_ALL''' in order to test code. The '''VtigerCRM''' install program requires production suited parameter values that '''hide useful error messages'''. Parameter settings should be set accordingly to coder needs while development is in progress.

The issue arises after a module is created recurring to the '''Vtlib''' API, while inserting a new record into the data aware form. Data are saved, but at save completion '''VtigerCrm''' returns a blank screen instead of the usual detail view. The issue is related to the new custom module and does not affect the standard software behavior.
