Dont mistake my post, this will happen after you add 4-5 campaigns, just installing the plugin its ok, the problem comes after when the campaigns run.
tried with external cron and different variations even altering everything on wordpress memory by configuring it and removing everything else from plugins and left just wpematico and wpematico+fifu even changed hosts this plugin cost me alot of time and money and effort before i come here, people must know before they rely on this plugin.

also it saves images rarely while they exists in the xml campaigns and you get F in gtmetrix cause its very hard to set the options to upload them in your server to the day i still try to configure this without success so the images load from other websites and your site will slow even more down at the point of 5xx errors database errors.
