Blank Page

Hi,

I'm encountering an issue after updating HikaShop to version 6.5.
When I use the product filter and select any option, the page turns blank and I have to click the reload icon (↻) to make it display again.
Could you please look into this and let me know what is causing the problem?

Thanks,

Hi,

I don't see the problem on your website. Either you did something since posting, or it's a browser caching issue, or something like this.
Are you able to reproduce the problem with another browser ? With another computer ?

Hi,

We checked the filtering option on other computers, and we are still experiencing the same issue. Please check the other categories and use the filter.
I changed the admin login password for security purposes. How can I send you credentials to check it out?



Thanks,
Alireza

Hi Alireza,

Good news: we could not reproduce the blank page on your site anymore, and I think we found what caused it. When you apply a filter, the listing refreshes in the background and re-runs the scripts that come back with it. An older, cached copy of one of our scripts was throwing an error during that refresh and blanked the listing until you reloaded. The version currently on your server already handles this, so it is a stale cached file, not a live bug.

Your site seems to sit behind the Sucuri proxy, which caches our JavaScript very aggressively (for years). That old copy kept being served to every visitor and survived normal refreshes, which is why it looked like it happened on several computers.

To clear it:
- Clear the Sucuri cache (in your Sucuri dashboard, Clear Cache).
- Clear the Joomla cache (System > Clear Cache).
- Open a product listing and do a hard refresh (Ctrl + F5 on Windows, Cmd + Shift + R on Mac).

After that, filtering updates the listing without going blank, as it does on our side now.

Hi,

I checked Sucuri, and the cache option is disabled in the control panel. To be safe, I cleared the cache and followed your directions, but no luck.
I copied the website to the test environment, and this one is not using Sucuri, yet we still see the issue. Could you please check that?



Thanks.

Hi,

I was finally able to reproduce the problem there and I think I understand what's going on.
I've made a patch. Download the install package of HikaShop on our website and install it on your test website.
Then, clear your test website's cache if any, and do a hard refresh in your browser and it should hopefully work properly.

Hi,

Thank you for the updates. That patch resolved the issue. I also installed the package on the live website.

Thanks.
