I have the same issue. It seems that installin the plugin causes a script that is used by ‘Visual Composer’ in the WordPress Disillusion theme causes this.
The standard picture slider apparently uses a similar setting or script, that causes the standard slides to narrow down to only a part of the screen – whereas when you deactivate the pluging again, the slider takes its original page width again.
I love the plugin, but as pinkish1 mentioned, I cannot combine it with my theme – any suggestions ?
Thanks!
