when i update pro version 7.2 , i noticed the WP dashboard become very slow , when i deactivate front end pm , the dashboard work normal , beside i still see this message in my site :
You have invalid or expired license key for Front End PM PRO. Please go to Licenses page to correct this issue.
Please make sure your website can communicate with other website. License is checked using wp HTTP request, so if it can not communicate with other website, it can not check license. Also i do not see any request for license check from your website.
Please give me screenshot of license page in settings. Also let me know your domain.
