 * I rec’d the following error today when I tried to run manually:
 * `Fatal error: Cannot redeclare class simple_html_dom in /usr/www/users/[.......]/
   plugins/postie/simple_html_dom.php on line 988`
 * The offending recently added plugin is:
 * **Category Specific RSS Menu || v1.13** <–Postie works when this is Deactivated
 * Let me know if there is anything I can do to use both the offending plugin and
   postie simultaneously.
 * Thanks

 * This is a bug in the Category Specific RSS Menu plugin. I’ve reached out to the
   author and explained how to fix it.
    In the meantime you will need to disable
   it to allow Postie to run.

 * I wanted to update you on the Cat Specific RSS Menu plugin. Apparently the author
   may have in fact made a change .. but it’s for the worse I’m afraid. At this 
   point, if that plugin is activated, and I click to run Postie (either regular
   or debug) it just freezes with NO ERROR. This is a problem I would assume.

 * Are there any errors in the server logs?

 * Simply
    `[Fri Jul 17 11:33:18 2015] [error] [client xx.xx.27.1] Postie: Checking
   for mail manually, referer:` or `[Fri Jul 17 11:37:03 2015] [error] [client xx.
   xx.27.1] Postie: Checking for mail manually with debug output, referer:` And 
   nothing after that either in logs nor on screen .. just dies.
 * Postie Test-Config works just fine and properly.
    deactivation of Category RSS
   plugin causes Postie to work fine and properly.
 * thanks

 * Is there another plugin you can use in place of Category RSS?
