# Known plugin conflicts?

 * I have the latest version (0.9.2.7) of this plugin on several sites which use
   the same custom theme. All sites are on WP 5.1.
 * All the sites are on the same hosting service. Two of them are in the same virtual
   service (one is a mirror/dev version of the other). The other is on the same 
   hosting company but a different server.
 * For the prod/dev mirrored sites, the dev version with W3 total cache works fine.
   On the ‘prod’ version (these are exactly the same configuration – just different
   dbs) any time I try to activate the plugin, I get a memory error only on the 
   admin side, not on the front-end. In the dev version of the environment, everything
   works fine.
 * On the other site, not on the same server, everything works fine.
 * I’m going nuts trying to find what could be different. It almost seems like there’s
   a conflict somewhere rather than an environmental problem, so I’m hoping there’s
   maybe a list of other plugins that have caused problems with this or something.
 * Any help appreciated

 * What is the specific error in the error log?
