Plugin not showing in article

I test zh map plugin on 2 joomla website
- 1 with clean setup of joomla 2.5, and plugin work great.
- 1 is upgrade from joomla 1.5 to 2.5, plugin not working, nothing happen (zh commponent still working normal)
How can I fix the upgrade site?

Hi.
Check that plugin is enabled.
Upgrade component and plugin to last versions in JED
Show you map, that you display by plugin as a component call (from menu call) and check browser console for errors.

If you think that's ok but not work - post me direct link to component and plugin call pages

May be there are a jupgrade links you not removed

Hi Dima.
Thank you for your quick response.
I think this problem is because Seblod component. When I restore the upgrade website to time "before install Seblod", Zh plugin work again.

What do you think about this?

I think it needs to test, does plugin work in there (Seblod) content, because if content stored in it's tables the my plugin may not work there. It works in 'content' type of data, and if Seblod can be proceeded by plugins with this type. Or it needs 'system' type.
