Plugin CP page causes white screen

Question

I'll start off by saying my plugin is working perfectly locally. The problem is when I upload to my server. My plugin is for a contact form. It handles the submission, and logs the entry in the db.

I have a page in the CP for it as well - this is the page that is giving me the white screen.

With devMode I am seeing this in the logs:

[error] [exception.Craft\HttpException.404] exception 'Craft\HttpException' in /path-to-my-site/craft/app/controllers/TemplatesController.php:59

So I looked up that file, and to me it seems that the system can't find a template?

I don't get any errors - although when I try to submit my form, I do get a 500 error. Could it be a permissions problem?

EDIT

Everything else in the entire site/app is working perfectly, so I know it's something with the plugin page.

My plugin "settings" page renders/works fine. It's when I click on the top "tab" to access my plugin's page within the CP that fails.

EDIT 2

I'm wondering if it's a case-sensitive thing now though. I don't see that exact error in the log file anymore.

I know with CodeIgniter, locally things work great, but when I upload to my server (CentOS) I get white screens. It's because of the case is all strange.

I have followed the suggested guidelines for plugin development:

controllers
    ContactFormPlugin.php
    controllers
        ContactFormController.php
            class ContactFormController extends BaseController {...}
    models
        ContactFormModel.php
            class ContactFormModel extends BaseModel{...}

   records
        ContactFormRecord.php
            class ContactFormRecord extends BaseRecord{...}
   
   resources
        ...

   services
         ContactFormService.php
             class ContactFormService extends BaseApplicationComponent {...}

   templates
       ...

   variables
       ContactFormVariable.php
           class ContactFormVariable {...}

...and so on.

My host is Rackspace, has anyone experienced this?

Answer 1

Brad, Thank you again for your help.

I found the problem, although I'm not sure of "why". In my service file, I have this line:

$email->body = craft()->templates->renderString($settings->welcomeEmailMessage, ['firstName' => $contact->firstName]);

After digging though log file(s), I found the error. "Unexpected '['"

It needed to be this:

$email->body = craft()->templates->renderString($settings->welcomeEmailMessage, array('firstName' => $contact->firstName));

Because everything was working perfectly on my local machine, (newer version of php) I wonder if that's the root cause.
