Title: Fatal Errors on PHP file Last modified: March 8, 2018 --- # Fatal Errors on PHP file * [suzannem2](https://wordpress.org/support/users/suzannem2/) * (@suzannem2) * [8 years, 3 months ago](https://wordpress.org/support/topic/fatal-errors-on-php-file/) * Hi, it was bought to my attention that the link to the telephone number which calls from a smart phone, was directed to the wrong number. I have no idea how this happened as I have never changed it. BUT, that said I tried to amend this by changing the number in the code in the php header and I am getting this error message; * “Unable to communicate back with site to check for fatal errors, so the PHP change was reverted. You will need to upload your PHP file change by some other means, such as by using SFTP”. * I have no idea how to do this! I am not a tech savvy person. Can you help using simple lehmans instructions please? * Many thanks. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffatal-errors-on-php-file%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 4 replies - 1 through 4 (of 4 total) * [paulwpxp](https://wordpress.org/support/users/paulwp/) * (@paulwp) * [8 years, 3 months ago](https://wordpress.org/support/topic/fatal-errors-on-php-file/#post-10052415) * There are clearly 2 problems here. * First your phone number on the site had been changed. Numbers don’t just change by its own, somebody had changed it, you need to find out if your site had been hacked or not. Meanwhile, the least you can do is changing your password, get a strong one. * The error message is common, it means there is a plugin conflict with latest WP version. Try installing this plugin and read the log, when you know which plugin had caused the problem just disable it. * [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/) * Thread Starter [suzannem2](https://wordpress.org/support/users/suzannem2/) * (@suzannem2) * [8 years, 3 months ago](https://wordpress.org/support/topic/fatal-errors-on-php-file/#post-10052938) * [@paulwp](https://wordpress.org/support/users/paulwp/) thank you for your help. I have installed the health check plug in and here is the log. I have no idea what to do with the information 🙁 How can I tell which plug in is causing the problem so that I can disable it? * PHP Version 5.6.33 – For performance and security reasons, we strongly recommend running PHP version 7.2 or higher.

It doesn’t allow loopback request which is a new feature in WP4.9 * See this reply [https://wordpress.org/support/topic/4-91-the-loopback-request-to-your-site-failed/#post-9866907](https://wordpress.org/support/topic/4-91-the-loopback-request-to-your-site-failed/#post-9866907) * Since the problem at hand is to change that phone number which is urgent, I suggest doing this: see to it that your theme has an option to change that phone number, theme might has this input setting somewhere. If you are positive that the phone number is actually hardcoded in the php template, then connect to the server via SFTP or cPanel (or whatever file explorer your server provides) and edit file using file editor there. * Important: it should be aware that we need to have full site backup (files and database) before making any changes to the site. Making a mistake editing file on a live site could ruin the whole site. Depending on the web hosting company, most do keep regular backup and also allows users to do the backup manually with just one click. * Thread Starter [suzannem2](https://wordpress.org/support/users/suzannem2/) * (@suzannem2) * [8 years, 3 months ago](https://wordpress.org/support/topic/fatal-errors-on-php-file/#post-10053301) * Thank you for your help.
