There’s one common problem everyone are currently facing using the most advanced content management system platform, WordPress, which is inability to save or edit main theme PHP files, especially after successful upgrade to WordPress 4.9 and higher. However, an absolute and instant fix has been tested and provided, based on my research.
I have seen same topics being created on different forums, seeking for a remedy but the solution is now available.
Moreover, this error occurred when my website was automatically upgraded to the latest version of WordPress 4.9. I was unable to edit and save my theme PHP files but instead, it keeps popping out with this same warning error after several troubleshoot below:
“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.”
This happens whenever I hit the “Update” button to save my files. It’s telling me to edit my theme via FTP but without the stress of using FTP, I later found an easy way to resolve the issue.
How to resolve the issue
Go to your Plugins and install new plugin called “Theme editor“, this will allow you edit and save your themes PHP file codes comfortably without using the FTP as requested by the WordPress version. Additionally, you can also use “WP Editor” plugin to fix the issue.
