Hi all.
I recently purchased this theme:
http://themeforest.net/item/folioway-pr ... eme/234219
and I really like it but I need s2member plugin to make it work for me. Problem is, everytime I enable the s2plugin it breaks the theme and gives me the "white screen of death." I'm running a local version of WP on MAMP/Mac enviornment. The theme works before I upload the plugin, breaks after I activate it, then works when I manually remove plugin. The plugin works on default themes that come with wordpress, which tells me it can work in a MAMP environment. I inquired with the theme owners and they didnt' feel that it was the theme that was bad but the plugin was doing something funky to it. They said that they'd work towards a solution if s2 community can figure out a problem with their theme. In any case, anyone have similar experience or recommendations? Not sure what other information to post, so if there is some tech info. that might help here, let me know and i'll post it. thanks for reading!

Try adding this line to your /wp-config.php file:

Code: Select all

define("LOCALHOST", true);  

s2Member has a special routine, which we refer to as the Systematics Routine. It sees your IP address is the same as the server's IP; which is sometimes an issue on a WAMP/MAMP installation. It's fine so long as your domain is http://localhost/. However, if it's something other than that, you'll need to add that line in your /wp-config.php file so s2Member realizes it's running on a localhost installation.

I don't know if it has anything to do with your theme, but I thought I'd mention it since you're using MAMP.

Now, when you say the theme breaks, could you explain what you mean? Do you have a screenshot? Do you get errors?

Hi Cristián,
Thanks for the reply, I really appreciate it. I didn't get right back to you because I was out for the holidays.

The local environment is indeed running from a http://localhost environment. s2member works just fine with another theme in the same MAMP install and set up. The problem happens when I enable the plugin. Everything goes white. I can't access any pages, even the admin page. I have to go in and manually delete the plugin for my Wordpress install to be accessible again.

Now, I can get s2member to work on the default WP theme in the same environment, no problem. And I can get the theme to work in the same environment. It only happens when I try and get the two to play together.

Any other thoughts or suggestions would be great. Not sure if WP generates error logs. if it does, and someone points me to thme, I can post when I go back in and activate the plugin which brings up the white screen.

I see, then it's a conflict between the theme and s2Member, is that what you mean? Watch this video and see if it helps http://www.s2member.com/options-page-di ... ing-video/

HI,
Thanks. Yes, you're right. it's a conflict between the theme and S2 member. I can't even get into the theme once I enable it. I get a blank white screen. I have to go in and remove S2 Member from the plugins folder to get my theme back. Not sure where to go from here when it' a theme vs. plugin conflict - where to look an where to adjust is the question I suppose. Any advise would be be great.

Also, it's a MAMP environment so maybe that also throws another wrench into the situation as well. I haven't tested the theme and the plugin in a live environment. UPDATE: just tested on live environment, broke theme once I activated plugin as well, with this error:

Code: Select all

Fatal error: Class 'iWaK_Cache' not found in /home1/halofdcc/public_html/mobiledemo/wp-content/themes/folioway/core/itools.php on line 75


Thanks!

error message:

BTW, tried the wp-config mentioned above; theme still goes white upon plugin activation. the authors of the theme said they'd welcome some insight if you feel the problems are on the theme side. This is what the theme author wrote regarding the error:

Code: Select all

Fatal error: Class 'iWaK_Cache' not found in /home1/halofdcc/public_html/mobiledemo/wp-content/themes/folioway/core/itools.php on line 75

'iWaK_Cache' is an essential class in Folioway, i don't know how and why it is not loaded (per the message you pasted) with your plugin. Please contact the plugin author first, i'd like to help if the author says the problem is on my theme, thanks!

Thanks for the updates. I'll notify Jason of this and wait for his comments.

Could you post a copy of the file that spits the error here so Jason takes a look at their code? Where the 'iWaK_Cache' class is and itools.php where it tries to use it.

You might ask the theme developer if his theme or any embedded plugins that he uses employs the use of PHP's "SPL Autoload functionality". If so, does he use spl_autoload_register(), or does the theme reply on a dedicated autoload handler? If so, please update the theme to use spl_autoload_register() to make room for other plugins.

Otherwise, if this does NOT help you any, please ask the theme developer to contact us. We'll be happy to provide a free copy of both s2Member and s2Member Pro for them to test against. Please ask them to use this private contact form: http://www.s2member.com/contact/

Thanks Cristián and Jason. Thanks for the help. I posted in the theme developer's forum. I imagine they'll respond shortly either there or contact you directly.

Here is the itools php file from the theme that seems to be spitting out the error. Thanks for taking a look! I really appreciate the time and attention,

Hi,
an update to the theme worked. FYI, here is what the theme developer wrote:

It was found the affected part in Folioway was the classes loading process that using the PHP native function __autoload(), and the function stopped working with several plugins for unknown reason.

Here a custom classes loading function was introduced to replace the native one in Folioway version 1.1.8, upgrade your Folioway to this latest version and your conflict issue gone

thanks for everyones help!

Great! Glad it got sorted out. Thanks for the update.
