How to enable WP_DEBUG ?

Hey guys, nice job with s2Member. It works great!

I have a problem: I’m developing a website and need to turn on WP_DEBUG, but when I do I get dozens of errors from s2Member (please see http://postmy.info/misc/s2Member-errors.png).

I’ve tried the define(“LOCALHOST”, true); trick, and while that clears up a few, s2Member throws many, many more. I know this is claimed to be fixed and I am running Apache > 2.2. But yet this still throws errors on my localhost and on live servers. To replicate the problem is easy:

1) Installl WordPress
2) Download and install s2Member (latest version 120309)
3) set WP_DEBUG to true

A google search for “wp-content/plugins/s2member/includes/classes/cache.inc.php on line 97” takes me to this forum where it claims to have been fixed but that clearly isn’t the case :-(

Is website development debugging just not supported?

Regards,
Steve

hello
I have the “same problem”
WordPress 3.4.2.
WP_DEBUG : true

Notice: Undefined variable: cache_needs_updating in ....../wp-content/plugins/s2member/includes/classes/cache.inc.php on line 97

and also

Notice: Undefined index: page in ......wp-content/plugins/s2member/includes/classes/admin-notices.inc.php on line 136

I’m developing on real server, with Apache 2+
I turned all other plugins off, but still. I do not know if it causes any real problems, because I haven’t chance to test the site fully (it is not ready yet).

Hello Stephen, 2046,

What happens if you update Apache to version 3+?

EDIT: Oops, didn’t notice the original date of this. :P

hello, Don’t know what happens on Apache 3+
And I’m not gonna try it. There are many websites running on the server and I do not want to brake any of them.

Unfortunately it looks like s2Member developers created the plugin with a complete disregard for WP_DEBUG. It doesn’t appear that they have ever turned it on themselves or have chosen to ignore the output assuming the average user of their product wouldn’t be doing such development (highly unlikely, if you are using s2Member then you are probably a developer).

The number of warnings that I’m seeing are because of ambiguous references to (possibly) global variables or items that are just un-initialized. I’ve written the authors about this:

“Undefined variable: cache_needs_updating in cache.inc.php on line 97. Please initialize the variable with a default value at the top of the function block (probably cache_needs_updating = false) or define it as global (which it probably is not).

We’ve got lots of debugging of our own stuff to do and these unnecessary notices are interfering with header transmissions, etc. Please fix in next release please.”

Unfortunately for every one I fix, more and more keep popping up. This makes using WP_DEBUG virtually impossible without first deactivating s2Member, which isn’t a great option if you are trying to create a website.

Hello Stephen,

Yes I understand, I already told Jason and he answered me that the next generation of s2Member is gonna fix all of this, in general it’s gonna be much better coded. :)

in other words.. it is not any crucial problem. it just messes up debugging, right?
If that is the case, then I can live with that for now :)

That is correct 2046. :)
