The shopping cart has been exhibiting some strange behavior recently, and I can’t put my finger on the problem. It seems to have something to do with cookies and caching, but I’m not sure. When an item is added to the cart, such as from this page:
It shows up properly in the cart. However, when subsequent items are added from the same page, they don’t appear in the cart on the sidebar. If I then navigate to other pages, the previously added items start to appear in the cart. Similarly, if I try to add a book to the cart, such as
it won’t show up in the sidebar cart until a few clicks later on another page.
In general, the main shopping cart page [http://www.cambridgelsat.com/shopping-cart/] has been working properly, but even it has shown some inconsistency.
I have W3TC enabled, the lines were added to the rejected cookies field, and object caching is disabled. The host uses Varnish, so I’m not sure if that could be contributing to the issue. Thank you.September 25, 2012 at 2:41 am #20723
This would most likely be a result of the customization you made to the plugin earlier. See your other post here:
Have you tried loading a fresh copy of the eStore plugin?September 25, 2012 at 4:00 am #20724
I don’t believe that’s the issue; I set that back to ‘0’ to no avail. I’ll try to upload a fresh build and see if that fixes it, but I think it may be something else since I don’t recall this happening before. I’ll keep you posted. Thanks.September 25, 2012 at 6:39 am #20725
As I suspected, the upgrade to the most recent version (6.9.1) did not fix the issue. To clarify, it isn’t an issue of adding the same item to the cart twice; I definitely want to prevent that, and have specified so in the plugin settings. The problem is that as additional items are added, they aren’t showing up right away. They’re showing up after a few more clicks while on other pages.September 25, 2012 at 4:33 pm #20726
It was Varnish after all. Once the host turned it off, everything started working properly again. Thanks for your help, and sorry for the trouble.October 31, 2012 at 2:11 pm #20727
I’m not sure where to post this so posting here. I have W3 Total Cache installed, everything actually works fine. I had to deactivate it yesterday to troubleshoot a WPMU plugin with the WPMU support staff, and when I deactivated it, people clicking on an encrypted download link to get a purchased PDF file got a screen full of gibberish. When I turned the caching back on, everything was fine. Just wanted to report the behavior in case somebody turned their caching OFF. I’m not sure what caused the behavior, but it works great when it’s ONNovember 1, 2012 at 2:54 am #20728
@peeld, It would be a combination of the following:
– The download settings you have configured in eStore
– .htaccess file modifications made by you and/or the cache plugin
– gzip compression settings
Basically, you have made some configuration changes over the course of your usage to make everything work with W3 Total Cache plugin. If you deactivate the plugin then you also need to revert some of those configuration changes back the way it was, otherwise you may see the issue you saw.November 1, 2012 at 2:24 pm #20729
Thanks. I’m looking through and am not sure where the settings changes might be. I did look in the download log and I just generated this:
[11/01/2012 2:19 PM] – Status : Unresolved DL file path = http://www.mysite.com/e-books/ClearMindSample-Chapter1.pdf
[11/01/2012 2:19 PM] – Status : Resolved DL file path = /home4/username/public_html/e-books/ClearMindSample-Chapter1.pdf
[11/01/2012 2:19 PM] – Status : Dispatching DL method = 1
[11/01/2012 2:19 PM] – SUCCESS : DL completed with no server-side errors detected.
But got the garbage output. Any advice is appreciated. The caching plugin is not coming back, it has created mass havoc in my site and I’m wondering if it wrote something to your plugin. I’m actually going to reinstall the plugins to see if that helpsNovember 1, 2012 at 2:44 pm #20730
Update: I reinstalled both estore and pdf stamper and this is an image of what I am getting:

Something is definitely going on, it’s like the server can’t parse the file or something. Is there some sort of library or something that I should double check is installed on my server?November 1, 2012 at 3:23 pm #20732
Another update, changing the download method generated no errors except for method 8, where a fail to resolve DL path error was thrown.
SOLVED – deactivating and deleting W3 TC caused some corrupt theme files which were the cause for the garbage pdf outputs. Phew!January 10, 2013 at 4:11 pm #20733elehostMember
Using WP Lightbox Ultimate and the W3 Total Cache 0.9.2.5 in WordPress 3.5 seems to give missing options settings in the settings page (due to caching). Is there an easy way to get it not to cache these admin options pages to avoid this issue?January 11, 2013 at 12:28 am #20734January 13, 2013 at 12:13 pm #20735Robert.GMember
I am running WP eStore, eMember and WP Afilliate. I have just installed W3 Total Cache and the dashboard warning directed me to this part of the forum. I have added the 3 lines of code in the first post on this forum to the W3 Total Cache Settings…do I need to do anything else.January 13, 2013 at 11:34 pm #20736
