Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
It is recommended to fill in the following
Post link:
SSH IP address, account password and port:
aapanel login link address and account password:

No post link will not be able to know which user's information is, and the problem will not be processed

After adding the # comment and deleting the functions prohibited by putenv, it works normally.
Note that putenv has been added back

aaP_evanv25

aaPanel_Kern so my issue was a php setting issue?

aaPanel_Kern

The result of the troubleshooting is that there is a problem with PHP settings.

I'm having the same problem only php 7.4 works fine php 8 and above versions have the same problem as here

aaP_agezer1985

I cannot install WHMCS on PHP 8 or higher versions; it is not compatible.

aaP_agezer1985

Is there anyone who can install whmcs in php 8 and above versions

aaPanel_Kern

Hello, please check whether you need to install the corresponding extension?

aaP_agezer1985

I don't understand what you mean.
if you try with aapanel php 8 and above whmcs will not install

aaPanel_Kern

Please check whether the PHP extension meets the running requirements. You can go to the app store to find the corresponding extension for PHP installation.

aaP_agezer1985

yes it is compatible with php 8 and above versions but it is impossible to install aapanel, installation is successful only in php 7.4 and lower versions

aaP_agezer1985

If I give you access information, can you see what the problem is and why it won't install?

I sent you login information

aaPanel_Kern

Hello, turn off the prohibited functions and restart PHP and it will be normal.

aaP_agezer1985

yes thank you, it works now...however, although disable_functions is open in php 7.4 version, the installation goes smoothly in it.
