Hello @LaDeessa,
Thanks for updating the thread.
I first removed the existing copy of Visual Composer and then reinstalled from X > Validation > Extensions but the error message was showing up upon trying to activate VC. I then renamed the Visual Composer folder from FTP and then deleted the same from WordPress plugins section. After that I manually uploaded the plugins files using FTP but error message was still showing up.
Next, I deactivated X Theme, Cornerstone and reactivated default theme. After that I reactivated VC and it worked fine. To narrow down the problem, I reactivated Cornerstone fist and then the parent X Theme and Visual Composer worked fine. However, when I activated the Child theme error started showing up. I had to rename VC folder and when I checked the child theme, it seems that you have made customization related with VC.
Now, we can’t provide support for customizations as it falls outside the scope of support we offer. So for now I have activated Visual Composer and parent X Theme. Visual Composer is working fine and there’s no issues. Regarding the changes, may be you can remove them or get some help from a developer.
Thanks.
