Magento

After blank pages yesterday, I moved to set up two clean installs of Magento. One is local, running MAMP Pro and one is on my dedicated-virtual server at (mt). I’ve pored over documentation and the forums and everything was clean. I’ve run the latest upgrades via pear successfully. I’ve been clicking all over in the admin changing settings and then, suddenly, on both sites on my server, magento is serving up blank pages.

I have modified memory_limit to 128M in php.ini AND the htaccess file for each site. I’ve restarted the server multiple times. Why does this keep striking?

Here’s the error logged when it occurs:

[Wed May 28 12:14:05 2008] [error] [client 64.25.81.82] PHP Fatal error: Class ‘Varien_Profiler’ not found in /var/www/vhosts/store.rubiegreen.com/httpdocs/app/Mage.php on line 47, referer: http://store.rubiegreen.com/index.php/admin/system_config/edit/section/design/

I’m staring at blank pages on two different URLs. I can’t look at the admin or the front end of the sites. Server resources are fine.

I set display_errors on in php.ini and restarted the server and now pages are loading. This is driving me crazy. Why is that error occuring??

If you are running APC or other bytecode cache, you might need to restart web server after you move or change files or directories.

Hi Moshe,

The server is not running any cache utilities. Magento is, though, right?

Thanks,
Mark

Your site is coming up ok for me.

You might want to delete the contents of your session and cache directories in var if you are continuing to experience problems.

Thanks for the suggestions.

I actually ran a load tester on it for a while after the last restart and its been fine. The questions:

1. Why are the restarts required *and* why I have been working on this for 2 weeks now and only seeing blank (suppressed error) pages as of yesterday? Even after bumping up mem limit.
2. I have two domains running on the dedicated virtual, with Magento sites working. Two databases, two sets of files. When one went down today, the other did as well.

What I’m getting at is this - I’m setting up a local dev environment, and will maintain a staging URL to deploy code to and test, as well as for testing upgrades. But if that kills both installs on the server, and I’m hosting more than one client on my dedicated virtual server, I’ve got a problem if restarts are required.

Thanks again for the help.

Mark

I just hit the URL now and it’s blank. I’ve made *no* changes to the site this morning. Things were fine last night.

Cache and sessions files deleted.

No changes to the site files or config since yesterday, was working last night.

Blank pages are gone—for the timebeing—as I turned off Safe Mode systemwide (php.ini) and restarted the server. Will continue monitoring. Still wondering what the deal is.

Was safe mode on?  Magento will not run if safe mode is enabled.

Moshe - 11 September 2007 02:20 PM

Magento will not run in safe mode.

This page: http://www.php.net/manual/en/features.safe-mode.functions.php shows that absolutely necessary functions are disabled in safe mode, such as:
header(), fopen(), move_uploaded_file(), unlink(), etc.

My guess is that more likely the ‘fix’ was restarting your web server.  Ultimately, this most likely means that something is misconfigured and your Apache is dieing over time.  Likely, a memory related issue.

I was toggling it off in the Plesk panel for each domain, assuming that would take precedent over anything global. Like I said, the site *had* been working fine prior. Perhaps that was when it was on an exclusive IP setting and the only site on the dedicated-virtual server. Current scenario was:

Two Magento sites on the server
Shared IP pool on the server
Safe Mode ON in PHP.ini
Safe Mode UNCHECKED (off) in domain setup for each site

They’d cruise along for a few hours or more and then start throwing blank pages.

As I said, I’ve now turned Safe Mode OFF in php.ini as well. The restart is what has things working again. We’ll see how long this lasts.

Yeah. It’s back. I just saved an edit to a template file over FTP. Safe Mode is off via php.ini, and errors are now on:

http://rubiegreen.slimkiwi.net/east-village-1.html

It’s not Apache, as other sites are running fine. Return times are fine. All resources on the server are well within limits.

After reading this post - http://www.magentocommerce.com/boards/viewreply/25498/ - I put the following

into index.php before

It’s working again, without restart. Still looking for a real solution. I don’t like the idea of keep tracking of hacks to the ‘system’ .

It looks like there’s “/lib/” in include_path - please create phpinfo.php, put it in Magento’s folder and post a link.

Spoke too soon!!!! Now getting:

I have a 6/9 deadline to launch a Magento site. Can anyone help with this?

Hi Moshe,

here’s the phpinfo link: http://rubiegreen.slimkiwi.net/cfg.php

Please note that *this* is the real issue. What you saw was the result of an attempt at a fix from another thread:

I saw in that thread that there may be a PHP 5.2.5 bug problem impacting Magento. Is that a known issue?
