WordPress® for Zen Cart® (wp4zen) [Support Thread]

[lhungil]

Sorry for the delay in replying. I can confirm that disabling this does allow google / websniffer to do its thing. I turned it back on for now just in case and will see what else I can find out

My best guess is: One of your WordPress plugins relies upon an active session (and starts one when a session is not present). When you have Zen Cart configured to "Prevent Spider Sessions", no session is started and output may start before WordPress is loaded in "html_header.php". This then causes a PHP error, because the output occurred before the WordPress plugin attempted to start a session.

If the above guess holds true, simplest fix is to allow Zen Cart to start sessions for "Spiders" (these include SE bots/crawlers). Because when a WordPress plugin requires the use of sessions, the gain from preventing spider sessions in Zen Cart will be minimal. A more complex fix is to determine which WordPress plugin is attempting to use sessions, then replace with a different WordPress plugin (which does not require sessions) or modify the WordPress plugin to also detect and prevent spider sessions.

Since the change to the html_header.php required for this module only adds a call to the WorPress wp-load.php file in Zen Cart (required so this module can display the WordPress sidebox content inside Zen Cart), I can't help but wonder if the errors you are getting are ACTUALLY coming from your WordPress blog..

Agreed, probably from one of the installed WordPress plugins. I've posted my stab in the dark above!

... I have been trying to do some log error solving, and it is still the same. ... On the zencart side, the only thing I have noticed since also December (weird) is that error logs are not being created. ...

The out-of-box WordPress disables portions of PHP error reporting. This will result in overriding of the Zen Cart PHP error reporting. When trying to track down an issue / error, one can add the following in "wp-config" to have WordPress enable all PHP error reporting and save them to a file (debug.log). Be aware the error log will probably contain a larger number of warnings about the use of deprecated functions/methods (these are not going to be the cause of the HTTP 500).

I would caution against leaving WP_DEBUG enabled on a production server unless one understands the ramifications.

/**
 * For developers: WordPress debugging mode.
 *
 * Change this to true to enable the display of notices during development.
 * It is strongly recommended that plugin and theme developers use WP_DEBUG
 * in their development environments.
 */
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

NOTE: Reference Debugging WordPress for more details regarding the above options.

Thanks ever so much for your insight and help. I think you are spot on, this is the last ever error log received from 14th December:-

[14-Dec-2015 15:25:22 UTC] PHP Warning: session_start(): open(SESSION_WRITE_DIRECTORY/sess_90b148a11e8486d7a845e635fefa1e12, O_RDWR) failed: No such file or directory (2) in /*******/public_html/******/wp-content/plugins/my-blog-guest/common.php on line 9
[14-Dec-2015 15:25:22 UTC] PHP Fatal error: Call to a member function count_contents() on a non-object in /******/tpl_header.php on line 107
[14-Dec-2015 15:25:22 UTC] PHP Warning: Unknown: open(SESSION_WRITE_DIRECTORY/sess_******** 2, O_RDWR) failed: No such file or directory (2) in Unknown on line 0
[14-Dec-2015 15:25:22 UTC] PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (SESSION_WRITE_DIRECTORY) in Unknown on line 0

I have turned spider sessions on, and hopefully not too much SEO damage has been done. I have resubmitted the site and sitemaps, and be vigilant on this in the future. I am certain this must be the culprit plugin, so it is best I remove as soon as I can.

Hello again,

Just wondering if the only way to regain zencart error reporting (on zencart specific errors only) is to disable wp4zen and put wordpress back into its own database and folder again? I tried the config as above, and you are right, it is wordpress only errors and lots of them.

Many thanks in advance.

I just figured it out, the wordpress sessions error created a massive amount of debug logs, so hopefully the host can delete most of them and I can start seeing error logs again.

What will REALLY resolve your issue is to find out which WordPress plugin is the cause of the issues to begin with. WordPress running in it's own database will not solve the REAL issue you have here.. (an errant WordPress plugin). Moving WordPress to a separate folder & DB and disabling this module will only MASK your issue because you will stop seeing the errors that will STILL be generating. To solve your issue once and for all, disable ALL of your WordPress plugins and re-enable them one by one to see which one is the root cause.

I really like the look of this mod. Currently using zc 1.5.4 with Winchester Black responsive and running a blog separately. Planning the update to 1.5.5 when released and do some mod changes at that time. I'd like to dump my cumbersome blogspot blog and put wp in my zc server.

Does/should this mod work (correctly) with responsive templates?

Thanks

This is not an "embedding" module -- because IMHO embedding modules are cumbersome and ultimately a disastrous method that is mostly used to avoid doing the work to make ones WordPress blog look like their shop.. This a much simpler module that provides a solution to integrate WordPress & Zen Cart. It adds Zen Cart sideboxes which contain WordPress content. So it works as well with any responsive template as any other Zen Cart sidebox.

Thanks for your help, appreciate you taking the time to reply. I found which wordpress plugin it was, and now removed entirely. They updated the plugin in December, but with a bug I guess.
