Hi,

I created the thread on the LiteSpeed forum (as RobertG).
I didn't test the frontend.
Two days ago I sent an email with all data to access the backend of a test site. I hope that the staff will find how to solve the errors.

[Darko-F]

@fontanil do you see front end in console headers "hit" "miss" from lite sped server or is this unique for me.?

[fontanil]

Sorry, I don't remember how to see headers informations.

On the frontend, page of Virtuemart main category, I have the same message (Call to undefined method Joomla\Event\Dispatcher::register() ) than in the administration.

From a non-logged-in (or private) browser, navigate to your site, and open the developer tools (usually, right-click > Inspect).

1. Open the Network tab in console.
2. Refresh the page.
3. Click the first resource. This should be an HTML file. For example, if your page is http://example.com/webapp/, your first resource should either be something like example.com/webapp/ or webapp/.
4. You should see headings similar to these:
   X-LiteSpeed-Cache: miss or hit

https://docs.litespeedtech.com/lscache/lscjoomla/installation/

Hope this help.

Thanks Darko-F,

I find only "Server : Litespeed", not "X-liteSpeed-Cache"
"date: Mon, 06 Mar 2023 12:45:53 GMT

nothing else

[Darko-F]

Ok thanks
We can confirm then that is this issue connected with error above, I assume that when this will be fixed also X-LiteSpeed-Cache will work.

I wonder why my host didn't stick to Apache and Memcached, is pain to configure these lite speed, plugin never work us is described, the last time when I try to work with on J3 I just uninstall it to hard to configure it correctly on complex site. Unfortunately I have bigger site to work with, so I need some kind cache.

[fontanil]

On another website (same server, same Joomla! version and PHP version) without Virtuemart, I don't find the line "X-liteSpeed-Cache", too.

[Darko-F]

I see, I try plugin only with one website so according theirs document nothing is cached try enter your website URL here https://check.lscache.io/ and see if work

I submit #58
