Conflict with the nextgen gallery plugin and Hyper Cache 3.x

Hi it’s hard to say why that happens, since Hyper Cache DOES NOT change the html code of the page.

To debug the problem I really need a live test case with Hyper Cache active and a post where the problem appear. And, of course, a “live” session with you to enable and disable the plugin to annotate the differences.

If you have the plugin enabled AND you get the stacked images AND you add some parameter to the URL like:

https://www.mysite.com/this-is-a-post?param=1

Do you note some differences?

I can certainly send you admin access to a live test site I setup. It is pretty easy to replicate the issue to be honest so you should see it in action and I can send you access login details for the test site if you wish which is an exact replica of the live site and we can play with this? Do you have an email here?

Here is the live link https://www.jamjosandbox.com/european/photo-gallery/ and as you can see the images are stacked vertically down the page. Then when you deactivate hyper cache is works well. 2.9.1.6 of Hyper cache is not a problem and works well so I can revert to this for now on the live site. I can give you access to this test site if you wish. the only 2 plugins active on that link are nextgen and hypercache and I tested with 2014 default wordpress theme also.

Hi empty the cache and empty the browser cache as well. It will work. Let me know, I’ve just tested and old cached pages seems the problem.

ok I will try. First I have clicked the “Clean the whole Cache” button. Where else do I clean the cache, maybe via FTP and deleting a folder for example? If you explain a little more I will try. I have emptied the browser cache on my browser but that is not working here.

Try to open that link:

https://www.jamjosandbox.com/european/photo-gallery/?p=1

does the gallery look good?

When I click on the link you provide I get this exact page here: https://i58.tinypic.com/123mvqb.jpg error 404

Sorry, try that:

https://www.jamjosandbox.com/european/photo-gallery/?aaa=1

No problem. I can confirm this works https://www.jamjosandbox.com/european/photo-gallery/?aaa=1 and this does not work: https://www.jamjosandbox.com/european/photo-gallery/

So how do I get this one to work here: https://www.jamjosandbox.com/european/photo-gallery

What I have done is clean the cache through the plugin button. Also cleared by browser cache on my computer and my system cache on my computer so I assume there is some cache file stuck on my website folder somewhere right?

I start suspecting you have an external proxy. Are you inside a company network? Or the cache cleaning is not working on your blog. When you clean the cache, the folder wp-content/cache/hyper-cache should be empty.

Ok so I have gone in here wp-content/cache/hyper-cache and deleted everything from it. Still no joy unfortunately here https://www.jamjosandbox.com/european/photo-gallery/

I am not inside a company network or proxy, I cleared my system and browser cache also. Are you seeing the page fine with the gallery thumbnails going across the page horizontally or is it like this screenshot? https://i58.tinypic.com/123mvqb.jpg

Hi, there is a number of stylesheet added in the non cached version. That means a plugin is buffering the wordpress produced page and it modify the code after the page has been generated. But even hyper cache buffers the page and probably it starts to buffer after the other plugin so it is unable to capture the whole page.

I can add an option to start the buffering early, even if it is not good for the cache performances… but the other plugin injecting the code should do it in the standard way using the “wp_head” hook. I don’t know if it’s next gen gallery doing that… may be it has an option for that…

Hi there, I have checked with the developers at NextGen gallery and this is what they have to say below so maybe there needs to be an option as you say to buffer earlier?:

“@allmyhoney – I did read that post, and can suggest the developer review the enqueueing processes to see if there is anything there to address but we do not offer any settings related to this currently.

– Cais.

Is this jquery conflict? Then apply below solutions jquery solution.
I had same problem in Business Website Design then I applied below steps

(1) Include prototype.js
(2) Find out conflicting jquery code and put in below section
var $j = jQuery.noConflict();
$j(document).ready(function() {

}

Hope this helped.
