This issue can happen when you upgrade php version. DevServer17 does not update correctly. I faced the same problem when upgrading php5 to php7 and then php8.
To fix the problem, perform the following steps.
Delete (or better, move somewhere else) the older php folders located in: C:\Program Files (x86)\EasyPHP-Devserver-17\eds-binaries\php\
Insert the correct php version in the server folder: C:\Program Files (x86)\EasyPHP-Devserver-17\eds-binaries\httpserver\apache2425vc11x86x241027114803\conf (note: apache2425vc11x86x241027114803 is the latest folder I installed, the name may vary depending on the version you are installing) by modifying the files "httpd.conf" and "httpd-php.conf" Insert correct php folder path in the server httpf conf files
Launch the dashboard. Devserver will prompt a warning related to the http server. Click on the tooth gear icon http server warning
Select the newly installed php version select latest php version
Everything should work fine now!
