Php error for output buffering

Cannot use output buffering in output buffering display handlers in
myserver/public/wp-content/plugins/s2member/includes/classes/utils-logs.inc.php
on line 75

Anyone know what this is about? Thanks.

There are several possibilities and, so far as I am aware, none are caused by s2Member:

  1. Are you running a caching or minification plugin? If so, try clearing the cache or resetting it.
  2. Are you running out of memory? Check how much you have allocated to WordPress. (Don’t rely on how much your host says it makes available to your site. Check it yourself.)
  3. You have a theme or plugin that’s doing something wrong. You wlll have to deactivate them all and reactivate one by one to discover the culprit.

yep, wp fastest cache. What doesn’t it like? Minifying js or Css?

I don’t know. I’ve never used Fastest Cache for more than a brief test, and I didn’t like it.

I always recommend Comet Cache, which has the added advantage here that it’s by the same developers as s2Member, so you know they will work fine together.
