RSVP Pro / hikashop breaking site

Hi,

For the first issue, please contact RSVP's support as we don't know how the integration between RSVP and HikaShop is done. It's completely on the side of RSVP so we don't know much about it and can't help.

For the second issue, this error comes from the AcyMailing extension. Please update your AcyMailing and if you still have the issue please report it to the AcyMailing support.

Hi,

That's because other plugins and components integrating with HikaShop are not up to date on your website or not compatible with Joomla 4.
When HikaShop needs to generate some HTML somewhere on the page, the first thing it does is loading the plugins integrating with HikaShop so that they can do their own thing. So, if at least one plugin integrating with HikaShop on your website is not compatible with Joomla 4, it will break the whole page as soon as HikaShop needs to display something on the page since it will load that plugin before generating the HTML.
That's why I'm saying you need to check with AcyMailing and JEvents since the error messages you're reporting on your HikaShop pages point at them.

Hi,

So if I understand what you're saying correctly and the message in your screenshot, the second issue with AcyMailing has been solved by disabling the "HikaShop trigger for AcyMailing filters" plugin, and so you only have now the first problem with JEvents and the "Please complete the Transaction Id field" message when adding something to the cart from JEvent.
As I said in a previous message here, for that error you need to check with JEvent.

In your latest message you're saying "any page that uses Hikashop is still breaking the site". But what error message do you have on these pages ? If it's the same message as you reported previously in www.hikashop.com/forum/install-update/90...verything-broke.html as I said, it comes from the hika_rsvp_redirect plugin. And so if it is up to date and you still have that issue, then you need to report the error to JEvent so that they can fix the issue. In the mean time, you can unpublish that hika_rsvp_redirect plugin via your Joomla plugin manager to not have the error.
But if you have another error, then I would need to know the error message you have to be able to tell you what to do.

Hi,

Looking at your latest screenshot, this indicates a fatal error during the processing of the page. In such cases, you should have the error message at the end of the page, supposing the "debug" setting is activated and the "error reporting" setting is set to "maximum" in the Joomla configuration page. So please check that these settings at set like that and look at the end of one of the pages with the issue to get the error message. With it, we should be able to tell you what to do.

If that doesn't help, and you still don't see an error message, please provide a backend access, a FTP access and precise instructions to reproduce the issue via our contact form so that we can look into it.

Hi,

I'm not able to acccess your backend with the credentials provided. Could you please double check them ?

Hi,

I was able to access your backend and check things out.
As far as I can see, it's the CSS/JS optimization mechanism of your template which is creating the problem for some reason. I went in the settings of the template and deactivated it and it now displays the same, regardless of whether you have the menu item enabled or not.
