500 Error on smaller server

    When using this plugin on a smaller server we get the following error on a empty cache hit (ie, one that tries to generate the cache)

    PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

    We have attempted increasing both the memory available to php and the swap in the system to no avail. Any pointers would be appreciated.

    The plugin works fine on a local server and on our larger live server, but we’d like to have this fixed as we don’t know why it is happening.

    I don’t think there is something we can do as the Cache Enabler depends on the ob_start function. Is any minification disabled? How much memory is available?

    Minification is disabled.

    PHP has 128MB of memory in php.ini (the same as live) and as far as I can tell there’s enough in the system/in swap for that.

    Any hints as to why a memory issue would give that response rather than a memory error?

    We found a solution. There was a permissions issue with our webserver writing to wp-content, so it was throwing a wp_die, and so causing the error.

    A suggestion for the plugin authors is somehow catching these errors so they can be logged in an understandable manner.

    For those with the same issue, check your webserver has write access to wp-content

    Im having a huge problem too. I was working on my site and when I clicked on the dashboard, I got kicked out and given a server error 500. I believe it is a problem with my theme installed. The problem is I can not even log in to uninstall the theme. Every time I get the Server Error 500. Please Help!

    nevermind, fixed
