Solution for this topic
like most changes with plugins, i test them on a copy of my site.
but it was the first time i try a plugin like this cache-plugin.
the plugin changed JS and CSS on my site.
On my test-site i haven’t any problems with it. but i think, the plugin works over time and had some influence on my site.
what i did now,
1) i removed the cache-plugin
2) I reworked the page on which i use the gillion theme elements and had to remove some “unknown” css code in the syntax from the gillion theme elements. also i found this tag [vc_column_text] [/vc_column_text] witch i have removed.
now, everything is ok.
thank you for your support
After some research i found the solution for my problem.
To update/reinstall the wpbakery plugin. I have to deactivate the cache plugin first. Then i had to uninstall the plugin ( v 6.0.3 ) and install the plugin from the theme ( v 6.0.2 )
The gillion elements works with 6.0.2 not with 6.0.3
But i have still a problem.
Is it possible that the shortcodes are not the same anymore?
