Cannot Access Protected Property

-- HikaShop version -- : 4.5.1
-- Joomla version -- : 4.1.2
-- PHP version -- : 8.1.0
-- Browser(s) name and version -- : Any
-- Error-message(debug-mod must be tuned on) -- : Cannot access protected property Joomla\CMS\Menu\MenuItem::$params

Hello again,

I created a Search filter menu item function per instructions I found on this forum and in the associated documentation. Unfortunately, I'm getting an error upon trying to Search on the front end: "Cannot access protected property Joomla\CMS\Menu\MenuItem::$params"

In an attempt to fix that, I broke my breadcrumbs - they don't follow the shop items, although sometimes it does and it'll stick on a particular item and not change. I've looked up this issue and have adjusted my SEF settings in HikaShop, but to no avail. I didn't mess with any CSS/PHP, but I also am not aware of any changes I made to breadcrumbs prior to the problem appearing.

Apologies that I cannot provide more information, as I'm not sure where to look. I've checked the logs and have tried inspecting the elements, but nothing stands out. I've attached the debug log for the error to this post - if there's anything else you need, please let me know. My website should be attached to this post.

Lastly, I'm wondering if it's normal to see so many "Deprecated" errors with debug enabled.

Thanks.

Nicolas,

Thank you. I've changed the statement to the one you provided. The search function appears to work perfectly now.

I'm curious: is it normal to have so many deprecations with Debug Site turned on; is it because I'm using Joomla 4.1.2? Will these impact the performance of my site at all - is it something I should seek a fix for? For example:

"Deprecated: preg_match(): Passing null to parameter #2 ($subject) of type string is deprecated in x/x/x/x"
"Deprecated: htmlentities(): Passing null to parameter #1 ($string) of type string is deprecated in x/x/x/x"

Apologies to pile onto this thread, but the code change did not fix the issues I am having with breadcrumbs in HikaShop areas. I can't really explain what it's doing ... it'll seemingly show breadcrumbs as if it were on a random item's product page. Other times it doesn't show beyond "Home / Shop." They also don't extend out when moving through categories. They appear to work as expected outside of HikaShop modules. As I mentioned, I've attempted 'fixes' I've found for general breadcrumb issues on this forum, such as altering SEF settings, such as Simplified Breadcrumbs, etc. I can't seem to find anything I've yet to try while I continue to scour the web.

I have a preproduction site (/preproduction) that I make changes to before altering the live site, and it doesn't have this issue. So it's very peculiar, as I wouldn't have made a change to the live site that could've caused it without also affecting my preproduction site.

Any ideas how to approach this issue? I'm not seeing anything on Debug or my site's logs (with Log Everything enabled).

Nicolas,

Thanks for the information. Per your request, here’s more information about those deprecations:

• Deprecated: preg_match(): Passing null to parameter #2 ($subject) of type string is deprecated in /home/user/public_html/administrator/components/com_hikashop/helpers/image.php on line 793.


• Deprecated: htmlentities(): Passing null to parameter #1 ($string) of type string is deprecated in /home/user/public_html/administrator/components/com_hikashop/classes/filter.php on line 1700.
