How do I debug this problem

[dreamer79119]

Hi,

 

I use prestashop 1.5.6.1

 

I Show my error report below:

 

Strict Standards: Declaration of FrontController::displayHeader() should be compatible with that of FrontControllerCore::displayHeader() in /hermes/bosnaweb06a/b641/ipg.reddoorcom/override/classes/controller/FrontController.php on line 119 Warning: Cannot modify header information - headers already sent by (output started at /hermes/bosnaweb06a/b641/ipg.reddoorcom/classes/Validate.php:1) in /hermes/bosnaweb06a/b641/ipg.reddoorcom/classes/controller/FrontController.php on line 639 Warning: Cannot modify header information - headers already sent by (output started at /hermes/bosnaweb06a/b641/ipg.reddoorcom/classes/Validate.php:1) in /hermes/bosnaweb06a/b641/ipg.reddoorcom/classes/controller/FrontController.php on line 640 Warning: Cannot modify header information - headers already sent by (output started at /hermes/bosnaweb06a/b641/ipg.reddoorcom/classes/Validate.php:1) in /hermes/bosnaweb06a/b641/ipg.reddoorcom/classes/Tools.php on line 130

 

Before this problem appeared, I just edit code Validate.php & form.tpl.

 

I used this teaching web below:

http://mypresta.eu/en/art/developer/prestashop-product-page-full-rich-editor.html#validate_class_change 

 

But it's no use and my web has something error.

How should I do to solve?

You likely installed a module that includes an override of the FrontController class.

 

In v1.5.6.1, the FrontController class has a function named displayHeader.  It takes 1 parameter as shown below

public function displayHeader($display = true)

You need to ensure the override that was installed has the same exact signature as this.

Hello,

 

I attach my PHP file in here.

 

I just edit this file only, I don't edit other files else.

 

Please help

 

Sincerely,

 

Validate.php

[vekia]

file is saved with coding: UTF-8 with bom

save it as a UTF-8 WITOHUT BOM

 

that's the case of headers already sent information

[vekia]

and regarding to the override:

you use Frontcontroller override as bellini mentioned

 

 

FrontControllerCore::displayHeader() in /hermes/bosnaweb06a/b641/ipg.reddoorcom/override/classes/controller/FrontController.php on line 119 

 

problem is also there, with this override

do you know for what purposes it is there?

note that some non-default module created it probably

do you installed some non default modules recently?

I already explained what you need to do to fix the override problem.
