Using WordPress 4.5 in combination with outdated versions of the LayerSlider and Visual Composer plugins can produce some serious bugs, including losing access to your WP-Admin section. If you need help solving these issues, please have a look at: How to fix issues after updating to WordPress 4.5.
If you have not yet switched to WordPress 4.5, we highly recommend you update your plugins and themes first:
- Layerslider: please update to version 4.11.2 or higher
- Visual Composer: please update to the most recent version
We also recommend you update your WordPress theme, as both plugins are often used in premium WordPress themes.
