Cannot View Products in Store after PHP 8.2 update

-- HikaShop version -- : 6.1.1
-- Joomla version -- : 5.4.0
-- PHP version -- : 8.2.29
-- Browser(s) name and version -- : Safari and Chrome
-- Error-message(debug-mod must be tuned on) -- : Cannot Decode Raw Data on Safari. The page is blank in Chrome browser. When I put it in debug mode, it works!

I recently updated to PHP 8.2 from 8.1 and now my shop is not working. You cannot get to the product page. You can see the shop but when you click on a product, either you get nothing in the Chrome browser or you get an error message - cannot decode raw data - in Safari.

When I turn on debug mode, the product is visible on the product page. Turn off debug, and you can't see it.

When I switched it back to 8.1, you can click on the product page. The problem with 8.1 is that Joomla warns you to update because it will not support 8.1 for much longer.

I thank you in advance for helping me with this.

Hi,

That's indeed strange. Nothing is returned by the web server on the product page but the listing page displays fine.
I don't see why that would be the case and I don't remember anyone else with the same issue.
This will require investigation.
The first thing is to check the error log of the web server and of PHP. Hopefully, it contains some information on what is going on.
I would also recommend you to contact your hosting provider to see if they can provide more information on why this URL doesn't display anything.

Okay, I contacted my host but they could not figure it out. I viewed the error logs and these are the only errors that show up so far.

Hi,

These are warnings and deprecated messages from other extensions. You can report them to their developer. They will be happy to know about it so that they can improve the code of their extension.
However, it should not change anything to your issue.

Can you try to switch to the default template of Joomla temporarily and see if that helps ? It could be a problem within the template, maybe a view override ?
Also, a temporary solution could be to keep the debug turned on and deactivate the system debug plugin via the Joomla plugins manager. That way, it wouldn't display the debug on the frontend but it should still work fine.

I switched to the default template and it still does not work.

When I tried your temporary fix, it did not work. Once I deactivated the debug plugin, I could not view the product.

I currently just have the debug on so the product can be viewed. Are there other options to get this resolved?

Hi,

Then it is difficult to solve without looking deep into it.
Please provide a backend super admin access (to check the settings if necessary during the analysis) and a FTP access (to add debug to narrow down the cause of the problem) and maybe an access where it is possible for me to switch between the 8.1 and the 8.2 during my tests if you don't want to leave it to 8.2 for 1 or 2 days.
Ideally, if you could make a copy of the website on the 8.2 environment so that I could look into it without impacting your live website, that would be even better.
Please provide that information via our contact form along with a link to this thread for reference:

I sent the email. Thanks!

Hi,

Sorry for the delay, I was not available to look into it at the end of last week and then there was the weekend.
I wanted to look into it today, but I don't see the problem on your website anymore.
I checked your backend and I can see that you're still on PHP 8.2.
So either you found the issue and the solution, or I'm missing something.

I understand the delay. I am just happy for the support.

The issue is still there. I just have it in debug mode, which is why it appears to be fixed.

Hi,

So, I didn't find the problem.
If I add an exit at the end of the frontend processing of HikaShop, I do see the product page content (without the template around). This means that the issue is not during the processing in HikaShop.
I also tried to switch to the default template just in case, but again, same issue.
So, I'm out of ideas on the causes.
So I've switched to the next best thing which is to make it work around the problem.
For that, I've done two things:
- I've edited the settings of the Joomla debug plugin and disabled everything there. That way, no sensible information is displayed in the debug bar at the bottom.
- I've added a piece of CSS to hide the debug bar.
So, right now, it works and the debug bar doesn't display. It's not pretty, but I couldn't find better. The problem is probably elsewhere on the website.

Okay, thank you so much. I will have to hire someone to look into this at some point. Perhaps with recent upgrades this issue will resolve itself.

In the meantime, would it be possible to get the documentation on what you did? I am asking because if I do have a problem on my site, I will need the debug to work properly. Would it be best to just upload a new version of the plugin? Of course, that will negate your edits. Or perhaps, I should just download the one you edited first???

Also, where did you add the css? Again, I want to know so in case this resolves itself. I can delete the code.

Hi,

I didn't change the code of the plugin. I only edited its settings via the Joomla plugins manager, and disabled them. So you can just enable them back if necessary.
Regarding the CSS, you can look at the HTML of the debug bar on your website via your browser inspector ( i.imgur.com/VvTiThc.png ) and you'll see I've added the code:
.phpdebugbar {
display: none;
}
