Today I migrated from Joomla 3.10.11 to Joomla 4.3 and my website pages (front) do not load when I go to any article.
I see error:
500 behavior::caption not found
when I go to any article.
this is due to the Rockettheme template or due to Gantry 5.
i have updated all extensions and plugins on my Jooml 4.3 website and if i change the default template theme to Cassiopeia then all the pages of my website load but if i change the template to Gantry 5 template the articles don't load on my website.
