After the Visual Composer update, sometimes there can be an issue when editing a post if WordFence plugin is active. The post editing can be stuck at assets download/upload.
The problem occurs due to a false trigger by WordFence plugin to block such operation. This can be handled by adding the following values in WordFence – All options – Whitelisted URLs.
| URL | Param |
| /wp-admin/admin-ajax.php | request.body[vcv-content] |
| /wp-admin/admin-ajax.php | request.body[vcv-elements-css-data] |
| /wp-admin/admin-ajax.php | request.body[vcv-zip] |
| /wp-admin/admin-ajax.php |
request.queryString[vcv-action] |
| /wp-admin/admin-ajax.php |
request.queryString[vcv-admin-ajax] |
| /wp-admin/admin-ajax.php | request.queryString[vcv-zip] |
| /index.php |
request.queryString[vcv-ajax] |
