# Plugin conflict / http 500 error

 * A conflict was just introduced after a recent plugin update. The conflict is 
   with Subscribe2.
    Subscribe2 is a plugin that allows users to subscribe to our
   blogroll via email.
 * I’m running:
    The Events Calendar 4.2.1 The Events Calendar PRO 4.2.1 The Events
   Calendar: Community Events 4.2.1 Subscribe2 version 10.21
 * Our site is [http://www.acadiarec.com](http://www.acadiarec.com)
 * When I activate subscribe2, the events calendar page does not display anything
   beyond the header. No calendar is displayed. When I try to load a page for a 
   specific event, I get an ‘http 500 error’.
 * I tried saving permalinks as per suggested here [https://theeventscalendar.com/support/forums/topic/http-500-error/](https://theeventscalendar.com/support/forums/topic/http-500-error/)
 * I also tried the .htaccess reset.
 * Currently, I’m leaving subscribe2 disabled so that the calendar appears, but 
   is only a temporary measure. Email subscriptions are a vital part of the success
   of our site.
 * Thanks,
 * Blair

    You can see the exchange I had on the Subscribe2 support forum here [https://wordpress.org/support/topic/conflict-47?replies=6](https://wordpress.org/support/topic/conflict-47?replies=6)

 * Hi [@blaircalgary](https://wordpress.org/support/users/blaircalgary/),
 * Thanks for reaching out and sorry to hear about this issue!
 * I’ve tried this in my local install (WP 4.5.3 – TEC 4.2.2 – S2 10.21) but couldn’t
   reproduce the issue. I just activated S2 and navigated the calendar in the front-
   end. Are there any specific steps I should follow?
 * Can you please check your server error logs for the error description?
 * Can you also please create a clean test site (maybe locally) and install TEC 
   + s2 latest with default theme and check for the issue?
 * Thanks,
    Nico

 * Nico,
    Thanks for the reply. I checked my server error logs and spoke to my host.
   They changed a few settings to no avail. Then I tried something which I have 
   not yet done: I enabled: Subscribe2 Events Calendar Events Calendar PRO I disabled:
   Events community.
 * Now both my Calendar & subscription management works, YAY!
    But I’ve lost my 
   ability to accept community event submission, BOO!
 * I can live with this scenario, but would be nice to have community working.
 * Thanks,
 * Blair

 * Hey Blair,
 * Thanks a ton for giving that a try!
 * We just released version 4.2.3 of all those plugins yesterday. Will you please
   update when you get a chance and let us know if you notice a difference?
 * Thanks so much!
    Geoff
