When i select on custom build in GUI, its showing PHP 80 and 81 have update. But when I click the update button, it will update and again it will show as same.
how to check it. i tried to install it first timemaybe you have custom_versions.txt in /custombuild dir with fixed versions?
this also checked.maybe you don't have this versions installed?
maybe you just selected them to install but not finished installation?
check "build software" tab
/usr/local/php80/bin/php -vso from SSH rename file versions.txt and run ./build update in /usr/local/directadmin/custombuild
