When I look at the source code of my ticket, it looks like this:

I can see link to first image but not QR code. Is this normal ?

Hey @Mattboggs,

The behavior you describe is not normal, and I have still not been able to recreate your issues. 🙁 I am sorry for this perplexing behavior!

We have already explored the possibility of a theme or plugin conflict, to no avail, so at this time the only other thing I can think of here is some server-related conflict. Perhaps your server is not allowing for the generation of the QR codes?

I would recommend contacting your web host to explore this possibility; share the issue with them and feel free to include a link to this thread for reference.

I am sorry for all of the trouble here!

Web host contacted (Godaddy) Here is a summary of what we discovered:
There appears to be some type of ‘caching’ taking place. Godaddy managed wordpress has an auto cache server so there seems to be a conflict with the generated QR image coming out. We disabled all plugins and also went to a default theme. The emailed ticket then looked fine. THis is the extent Godaddy could help me. One final note when the QR image is generated it has a ‘/?= ‘ added to the path which is causing the ‘404 no image’…..

Our assumption is; could your plugin be caching the image, conflicting with Godaddy’s cache ?

Well, I simply disabled my theme (Samsara)and went to a default theme with all plugins active and the QR showed up. Here is a link to the theme: http://www.themevan.com/item/samsara-creative-multiple-purpose-wordress-theme/
I have contacted them. Is there anything else I should try out ? The theme uses 2 plugins: Visual Composer and Revolution Slider.

Thanks,

Matt

Excellent find!

From here, the best thing to do is contact the theme authors for support and see if they can identify why their theme prevents QR Codes from being generated.

There is unfortunately not another step that I can recommend—but it’s a great step to be able to identify the culprit and I wish you the best of luck with your project from here.

Sincerely,
George

Hello again. The theme publisher has been very helpful but perhaps needs assistance from you. Below, I have copy\pasted our latest :

Everyone has been very helpful with this process and I will forward your request where I am sure you will get a speedy reply.

Is it possible to ask the plugin provider whether or not there’s any requirements to generate the QR code in the theme codes, because I haven’t added any codes to limited the image part, and I’m not sure how it generates the QR code. If the the plugin developer can give me a direction on how the QR generator works, that’s would be nice.

Sorry that this issue is really out of the theme development knowledge, but I will try my best to figure it out.

Thanks

Still no code (opened in Outlook as well as Gmail client). My associate in Chicago does not see the code as well. Bringing it up on a browser does not show code.

Hey @Mattboggs,

Thank you for your patience here over the weekend.

In regards to the requirements for QR Code generation, the codes are generated using this PHP library: http://phpqrcode.sourceforge.net/index.php

The requirements are basic GD and Image functionality on the server, functions like ImageCreate() or the ones listed here.

There are a few possible culprits to this which are neither from the plugin OR from the theme. I would recommend looking into all of the following things:

• Server permissions: the “generation” of the image may be fine, but maybe it’s just not being written to the uploads directory on your server or something? To rule this out, please contact your web host and ask them to ensure that your site’s WordPress uploads and wp-content directories are owned by server, with their permissions set to 755 recursively. If this does not help, proceed with the next step.

• .htaccess file: If server permissions are confirmed “okay” and issues persist, ask your web host if the site’s .htaccess file may be interfering here. This is not very likely but is worth ruling out. They may have custom rules in their .htaccess file—as if so, and if they could reset it to a “default WordPress .htaccess file” at least temporarily for testing.

• Server restrictions or missing libraries: or A final thing I can recommend here is to ask your web host if they can otherwise identify anything on their end of things (the server itself) that may hinder the PHP-generation of images as done by our plugins and their use of the “phpqrcode” library. They may be omitting certain common PHP libraries or server-side tools from their servers.

I am genuinely sorry about the prolonged and uncertain nature of this issue. I hope that the information above helps, first the information about requirements to respond to the theme author with, and then the information about further steps you can take with your web host.

Sincerely,
George

It’s ok, everyone loves a challenge, right ? I will forward your message to the theme creator as well as the host (godaddy). Once I have it all working again, I will send the solution here for your knowledgebase.

[George]

Sounds good. I will leave this thread open so that you can post any updates/relevant responses.

Sincerely,
George

No solutions yet from the host but here is what was found:

• Server permissions: the “generation” of the image may be fine, but maybe it’s just not being written to the uploads directory on your server or something? To rule this out, please contact your web host and ask them to ensure that your site’s WordPress uploads and wp-content directories are owned by server, with their permissions set to 755 recursively. If this does not help, proceed with the next step.

Uploads directory was empty…Host fixing and testing…One down.
When theme deactivated \ reactivated values in the wp database uploads directory emptied out (WP uploads directory and WP Dir. URL).

I am sending this info to the theme developer.

[George]

Thank you for the update!

[mattboggs]

I am happy to report that the problem is solved. The culprit was a long ago deleted plugin (17 months ago) that had a renegade PHP script still calling shots. In this case, preventing the QR to publish out in the open.

Thank you for your awesome assistance Sir.

Matt

[George]

Glad to hear it! Thank you for your patience and persistence here, Matt!

Open a new thread any time if other issues arise.

Cheers,
George
