Hi I installed Rosie theme (Version: 1.4) and Installed visual composer (Version 4.4.2). Website was working very fine for more than a year without any issue, but now while editing the pages, the visual composer not loading... I have attached the image.
This is how it looks now
try this step
You can upgrade Visual Composer by performing following steps:
Please make sure main theme is activated while performing other steps
Go to Plugins page in your WordPress Dashboard, locate Visual Composer in the list, deactivate it and delete it
You will see message that required plugin is missing at the top of your WordPress Dashboard
Install the plugin and then activate it
