Recently there is a problem on my website. When I wanted to edit my site, the visual composer shows nothing on the screen even I put on new elements. I can still click on the elements but nothing to show on the editing page afterwards. When I want to activate salient visual composer, there is also an error message showing as follows
Cannot redeclare class Vc_Manager in /home on line 35.
So I have gone through some of the suggestions which suggest that it may be due to plugin errors. I deactivate all of them but the salient visual composer.
I can only click on the button + of adding new elements, but then nothing to show on edit screen.
I think it’s gonna be the compatibility on the theme, so I click on the theme page and there is a message showing
The parent theme is missing. Please install the "salient" parent theme.
So how do fix it? this one does trouble me for a bit of time already T_T
