Hi, Guido.

Thank you for contacting us.
I assign developer to investigate this further.
He'll contact you ASAP.

Hi Guido,

Would you mind provide me FTP and backend access, please?

thank you!

I found out what is causing this problem. I have Widgetkit from YooTheme enabled (system plugin Widgetkit content). It has been working before, but since newer version of it it does not.

YooTheme is not responding so far. Can you solve it? Many are having this problem, also in YooTheme forums.

Hi Guido,

I am soorry, i dont have idea for this, I am not YooTheme expert.. I suggest you change the template or bump again their support.

thank you

YooTheme's Widgetkit is not a template. It's a component to build galleries and other stuff.
This problem only occurs on JomSocial's Events site, all other sites work. So there is a conflict with yours and their programming.

Maybe now you have an idea because your support is more responsible than theirs.

As I found out the pagination is causing this problem. If I uncomment this it will work for 5 events (next pages are missing of coure):

/components/com_community/views/events/view.html.php in line 313
// Get pagination object
$data->pagination = $model->getPagination();

Hi,

Have you checked this one :
yootheme.com/component/answers/question/75546
yootheme.com/support/question/83278?order=created

?

thank you!

Yes, thank you. Those are all old posts. In 2015 and 2016 the problem has already been coming up and could be solved by unpublishing the ZOO Widgetkit plugin for people who don't use ZOO component (including me). With the recent version of Widgetkit this is not possible anymore, because the system plugin already gives this error.

The problem is the pagination of events with Widgetkit enabled. Can this pagination be solved different?

Hi Guido,

Im sorry, I really dont have any idea for this, since this is coming from their plugin, and actually this issue is beyond our support scope. please you contact Zoo developer again.

thank you

I can not say who's fault this is, I can only say that many people are using JomSocial and Widgetkit so this got to be fixed. Since you can't fix it and YooTheme is not responding we users will be the ones who have to deal with it. So I can only show 5 events by commenting out YOUR code, because Widgetkit is used on many subpages and will not break after the customization.

Thank you for your time.

Hi Guido,

I suggest you change your template, that is wise solution, since we dont have any issue like this on another template.

thank you!

Widgetkit is not a template.

HI, Guide.

It seems that you become trapped between two developers. I'm sorry for this but please understand: it seems that issue is caused by Widgetkit. You mentioned in your first post: "It has been working before, but since newer version of it it does not." What actually means they cause issue with their latest upgrade... if so they should review their code and take a look what was changed... why it worked before and now not. The problem with Joomla! is that developers are playing with their extensions ignoring other components that may be used along.

I'm afraid we can't fix this as JomSocial didn't broke anything. I'm really sorry and I hope that Widgetkit developer will finaly take responsibility for that issue.
