Support » Plugin: Autoptimize » Getting an error when enabled on site

  • I enabled and set up this plugin on our site and it scored 100/100 on google page speed. I went to the site to check it out and got an intermittent error: Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0
    I’ve tried enabling only HTML, only CSS, and only JS, and I get the same error everytime. This plugin seems to do the job I wanted it to do, but it is breaking the site. We are running WordPress 4.0 with the Kallyas theme.
    Any help with this would be greatly appreciated.

    In general this vague error is due to a combination with another plugin which probably is using the output buffer as well. You could temporarily disable other plugins selectively to try to find the plugin that is incompatible somehow.
