Blank page

That’s weird, because all the CSS and javascript implied should really be scoped to the plugin’s HTMl part only.
CSS looks like
#this-page-needs-files TD { ... }

Javascript uses jquery and goes like
$('#this-page-needs-files ...

Do you have any error showing in the browser console?

Is the main panel really all blank (no editor, etc) or could it be that the content is just far away from where you expect it to be?

Hi ?? thanks for the quick reply …. there are no error messages

The main body panel shows nothing visually on the screen

Below is all the code from the body

Could you try editing “requirements.php” from the plugin this-page-needs-files directory and comment the second line (add two backslashes in front of it)?

<?php
\\defined('BE_MCH_TPNF')||die();

I’ll investigate what might go wrong about it in the meantime.

Hi ??

I tried the 2 backslashes and got this error message in the admin

‘Parse error: syntax error, unexpected T_NS_SEPARATOR, expecting T_STRING in /usr/local/pem/vhosts/166423/webspace/’

Aw, sorry, I meant (forward) slashes.

<?php
//defined('BE_MCH_TPNF')||die();

Maybe you could update your plugin to latest version (1.0.2) and see if it helps?

Hi ?? … I tried the forward slashes and still got the blank page

Then I updated to the new version and got this error (no blank page though)

‘Fatal error: Cannot access self:: when no class scope is active in wp-content/plugins/this-page-needs-files/model/urls.php on line 11’

Could you tell me “all” about your environment?

OS/PHP version/things you think might be particular/… ?

Can you download and try the 1.0.3 version, I made it to fix this issue*?

*this issue is not supposed to happen on PHP 5.3+ though.

Hi ??

Tried 1.0.3 getting another error for line 12

‘Fatal error: Cannot access self:: when no class scope is active in /usr/local/pem/vhosts/166423/webspace/httpdocs/Finedon2.org.uk/wp-content/plugins/this-page-needs-files/model/urls.php on line 12’

I don’t have anything unusual in my setup …. Im on an up to date mac … and have tested locally on MAMP and on a hidden test site in a live environment … both getting the same errors

Ok, well I’m currently clueless because I replaced static/self with direct call to the classes.

line 12 should be :

$class::$List = array_flip($instance->getConstants());
(maybe you could check on that)

I’ll get back in touch with you if I reach new enlightenment.

I think you use a buggy version of php where getConstants just crashes (this bug happened on some of the 5.3 verions of php).

I’m serious about this.

Could you try the new version?

And tell me if you get any error message.

I’m expecting you to have an error “This version of PHP doesn’t support getConstants”.

Since the issue came from PHP and not my plugin, I’m marking this topic as resolved.

Hi … sorry I haven’t come back sooner … I have been offline.

I have tested the latest version and it is now working for me ?? Nice work !!
Will run it for a while and see how I get on

Many thanks
