Issue:
You are using DirectAdmin with CloudLinux, and the exec() function is disabled in PHP 7.3. When you check your [phpinfo()] output, you see `exec` listed under disable_functions.
You want to enable the `exec` function.
Environment:
Solution:
1. Connect via SSH as root:
2. Find the correct config file that sets disable_functions:
Look for an output like:
3. Edit the php.ini file:
Find this line:
Remove `exec` from the list:
Save and exit (`CTRL + X`, then `Y`, then `ENTER`).
4. Refresh CageFS and restart PHP:
Alternative command if the one above fails:
5. Verify with phpinfo():
Create a file called `phpinfo.php` in your website’s public_html folder:
Open it in the browser and check the “disable_functions” section. `exec` should no longer appear there.
Notes:
- This method works only for alt-php versions managed by CloudLinux PHP Selector.
- If you're using a `.user.ini` or custom `php.ini` per user/domain, check those files as well:
