I added my remark to a thread that is set as resolved although it is clearly not so.
This was my remark:
Since the last upgrade I too have memory problems on sites that are on a shared server with 64 Mb of memory for each website. These problems were not there before, so I am wondering if WordFence is still the plugin to use in that setting.
If 64 MB is my limit, can WordFence still function? The "Maximum memory Wordfence can use" setting does not seem to matter that much. And, it is not quite clear what it means.
