1. Installation Failed. Forbidden. Error when Trying to Install the Extension from Vtiger Marketplace

This error sometimes occurs when processing credit card payments in Vtiger Marketplace. Check your credit card data. If the credit card is entered correctly, the only known solution is to try another credit card and create a new Vtiger Marketplace account. You may also want to contact Vtiger support in this case.

2. How to make Advanced Funnel Charts widget wider?

Unfortunately, Vtiger does not allow extensions to resize widgets. If you want to make Advanced Funnel Charts widget wider, you will need to add a small fix in Vtiger source code. (We do not recommend you do this if you have no at least basic experience in PHP programming).

Open file modules/Vtiger/models/Widget.php in Vtiger source code, find PHP function getWidth (it is located in the beginning of the file) and add ‘SPFunnelCharts’ in array largerSizedWidgets (needed modification is shown in bold):

public function getWidth() {
	$largerSizedWidgets = array('GroupedBySalesPerson', 'PipelinedAmountPerSalesPerson', 'GroupedBySalesStage', 'Funnel Amount', 'LeadsByIndustry', 'SPFunnelCharts');
	$title = $this->getName();

	if(in_array($title, $largerSizedWidgets)) {
		$this->set('width', '6');
	$width = $this->get('width');
	if(empty($width)) {
		$this->set('width', '4');

	return $this->get('width');

3. I do not see my funnels in “Add Widget” menu on Dashboard

Sometimes not all system files are regenerated properly after installation of the extension. To fix the problem, go to CRM Settings -> Module Manager, find “Advanced Funnel Charts”, uncheck checkbox (disable the module) and then check (enable) it again.

4. PHP Warnings are Displayed in Browser when Using the Extension

For production systems it is recommended to turn off showing warnings on web page and redirect them to server log by setting the following options in php.ini:

display_errors = Off
log_errors = On
