Bug with cookies / different browsers/computers

[damiende]

I have a weird issue;

I think its related to cookies, maybe.  (we're still in development)

When a product is added to the cart (using chrome, or any other browser)  - other users, cannot do anything with the cart system, products cannot be added on other browsers, or other machines.

After the cache is refreshed, someone can add product again to the cart, but if that person does, it stops working for all others. 

This includes people logged-into individual accounts,

--------------

Secondly;

When adding products to cart; and then signing in, the cart is put to 0 again.

Any ideas what could be causing this?


EDIT:   When 1 person adds X amount of products on the homepage shopping cart, someone else (on a different computer) can see the products added.  They're sharing the same homepage cart.      When changing pages to a category or products page, it changes the cart to your own.

Hi @damiende 

Made sure that the extensions you have installed is not messing with your cart or let me know if you have made any changes after which you are getting this issue.

@theMageComp 

I'm not entirely sure when the issue started happening, we just started in-depth testing now.

Using the following;

MageStore Onepage Checkout
MageStore Affiliate Program
J2T Points & Rewards
Owebia Shipping Module
Brim Full Page Cache
Presistance Shopping Cart = active

Other than that, I cant think of anything off-hand that could be causing it.  Or what file I should even look in?  Maybe a php error or something wrong with JS?

@damiende 

Try disabling the extensions one by one. I suggest you should start with the Brim FPC extension.

Disable extensions one by one and check wheather your issue gets resolved or not.

It's also possible that your extension is not compatible with the theme.

@theMageComp

I disabled all non-standard magento modules that didn't originally come with Magento 1.9.0.1

I even diasabled Cm_RedisSession  

The issue is still happening


Could I have a cookie setting wrong?
or HTaccess wrong?
index.php?

@damiende 

Back your files and "Run Compilation" and check if the issue is fixed or not.

If this doesn't work, we need to have a look for find the issue.

@theMageComp 

I attemped to run compiler, it failed very badly.

White screen, site crashed, msql down, 404 errors, unable to log back into admin frontend

I removed the includes folder trying to fix the issue, and now nothin works 


EDIT:  I did a full restore to where eveyrthing was 1 hour before compilation, now the whole site is broken, the compilation ruined the backup or something

[theMageComp]

Have you backed up you database as well?

[damiende]

@theMageComp 

Ok, I managed to get it fully restored, and working before the compilation.

I dont think compilation will work.

Anything else it could be?

Htaccess setting or cookies?  maybe varian.php?
