Some clients have report for me, and I go to Login as Owner and get same problem. please check the attach file , page load forever, while the page loads, i also can't load the pages in admin panel, for example: https://domain.com/clients/admin/clientssummary.php?userid=1020 , then i turned off the https://domain.com/clients/clientarea.php?action=services page and waited for about 1 minute, the admin panel pages loaded normally again. * This problem occurs only some customers (either new or old). *product or service : is the same, but only some customers have this problem. I have enabled Displaying PHP Errors but don't show anything. This is my hearth status : and my server is normal, only 30% capacity! Please help!
