I just upgraded to the Premium upgrade to better protect our site, hampshirereview.com. We’ve used Wordfence (free version) for about a year and really like the protection it offers. Lately, we’ve been getting numerous hack attempts via our login.php so we chose to upgrade and use the Country Blocking. After putting in the paid code and getting our settings updated, I went to our site and it’s blank. Nothing is there but the background. Everything else works fine in the dashboard, though. Oddly, we bought 2 API keys and installed the second on spiritofjefferson.com and it comes up fine. It has the very same settings as hampshirereview.com. I looked through the forums and saw there was something on upping the memory via our host. We are using 13GB out of 16GB of RAM. How much memory does this plugin require? I’ve removed the paid API key, returning back to the free key for hampshirereview.com for now so that our site stays up. Any suggestions or help would be much appreciated!
