Option Name Manager page displaying incorrectly

[AustinJim]

Hi,

PHP Version: 5.3.27 (Zend: 2.3.0) PHP Memory Limit: 90M
Database: MySQL 5.1.56-log

I downloaded and installed this manually. It has not yet been upgraded.

When I navigate to Catalog > Option Name Manager the page displays some large black blocks and the layout is so messed up that I can't do any editing. This also happens on the Catalog > Option Values Manager.

When I inspect the element using Chrome there is an img tag that looks like this:

<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAAAAACwAAAAAAQABAAACAkQBADs=" border="0" alt="" width="100%">

It seems like this img tag may be in the display of the header of the attribute list but i can't quite tell.

Does anyone recognize this or have any suggestions on what I should do next?

Thanks!

What version are you using, what addons are installed??

[AustinJim]

Sorry, I didn't include the version in the message. I thought when I selected it when posting it would include it. I'm using v1.51. The only plugin I have is Easy Populate.
Thanks!

Try reloading your admin files

I compared the files in production with newly downloaded ones and they are the same. But, I did find something interesting. Occasionally the page displayed correctly. It did this the first time I opened it in Firefox so I grabbed the HTML from the page. When I hit it again it exhibited the problem so I grabbed that source also. The difference that is causing the problem is in the img tag:
Code from working page:

<img src="images/pixel_black.gif" border="0" alt="" width="100%" height="1">

Code from bad page:

<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAAAAACwAAAAAAQABAAACAkQBADs=" border="0" alt="" width="100%">

Notice the difference in the src? I'm beginning to wonder if Zen Cart, PHP or Dreamhost is caching this and returning it incorrectly.
I believe the PHP from options_name_manager.php where the problem occurs is this:

<?php echo zen_draw_separator('pixel_black.gif', '100%', '2'); ?>

So, I can probably edit the source file and remove this to get a workaround but it may occur in other places in my installation and I'd like to understand what's happening.
Has anyone seen this or have any suggestions on what do to next?
Thanks!

I've seen that behavior on sites with mod_pagespeed enabled. You may want to ask your host if they have this installed and enabled.... And if you can have it disabled for the admin folder.

[AustinJim]

That worked! The actual solution was to put the following statement in the .htaccess file in the admin directory:
ModPagespeed off
Thanks so much for the clue.

That worked ...

Thank You for reporting back the issues were caused by mod_pagespeed. It's good to see your hosting provider allows you to modify the configuration settings using a .htaccess file

On the topic of mod_pagespeed, I understand why some hosting providers are installing and enabling this module by default. However, I'd estimate about 98% of the optimizations done by mod_pagespeed can be done by a competent Web Developer / Server Administrator without the need to rely upon the module to automatically "optimize" the site content "on the fly". In some cases the "optimizations" done by mod_pagespeed can be overzealous or actually cause problems.

Don't get me wrong, I'd not saying mod_pagespeed is bad... Just saying you will want to be aware of how it impacts your website... And take the time to learn how the module "optimizes" the site content... And then configure mod_pagespeed to better fit your websites needs (or possibly lack of needs if the site is already optimized)...
