 * Hi, I’m using Master Slider and I love it. But unfortunately, the plugin is causing
   a “Fatal error: Unknown: Cannot use output buffering in output buffering display
   handlers in Unknown on line 0” error. All my plugins, including this one, are
   up to date. Please help me out.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugins-causes-fatal-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi,
 * Thank you for choosing Master Slider.
 * I guess there is a conflict between your plugins. 
Please deactivate all the 
   installed plugins, except Master Slider. Then reactivate them one by one. After
   reactivating each plugin, check out and see if the issue persists.

    If the problem
   persists, you can select the default theme and check out again.
 * Please let me know the result.
 * Best,

 * Hi,
 * Thank you for your reply. Unfortunately, that’s exactly what I did and the problem
   still persists. I’m using Divi Theme btw.

 * Hi again,
 * Did you change your theme to default? Does the problem persist?
 * Also, what version of PHP are you using?
 * Best,
